As shown in fig. 1, in some preferred embodiments of a telescope according to the present invention, the telescope comprises a telescope body 10, an objective lens 40, and an adjustable eyepiece 30, wherein the telescope body 10 comprises at least one lens barrel 20. In the present embodiment, the telescope body 10 includes two lens barrels 20. The telescope body 10 is formed by connecting a left lens cone and a right lens cone through a connecting piece, and the lens cones 20 can rotate along the connecting piece. Understandably, in other embodiments, the telescope main body may include a single lens barrel, and the number of the lens barrels may be set according to requirements, which is not described herein.

The first end 201 of the lens barrel is provided with the ocular lens 30, the second end 202 of the lens barrel is provided with the objective lens 40, and a closed space is formed between the ocular lens 30 and the objective lens 40. Further, in order to improve the sealing performance of the telescope, nitrogen gas can be filled into the sealed space formed between the eyepiece 30 and the objective lens 40, so that the inner lens can be effectively prevented from growing mildews and mists in the future. Besides filling nitrogen, dry air or other gases can be filled, or a drying agent is arranged in the telescope to ensure that the inside of the telescope is kept in a sealed and dry state.

In the present embodiment, the eyepiece 30 and the objective lens 40 both include the antibacterial lens 60, and the antibacterial lens is disposed on both the eyepiece and the objective lens, so that the antibacterial performance of the telescope can achieve a better effect. Of course, in other embodiments, one of the eyepiece 30 or the objective lens 40 may include an antimicrobial lens 60, for example, the antimicrobial lens is disposed on the eyepiece, and the objective lens is disposed as a normal lens or some other lens without antimicrobial property; or the objective lens is provided with an antibacterial lens, and the ocular lens is provided with other functional lenses.

Further, the telescope main body 10 in the present embodiment includes two lens barrels 20, and a central focusing knob 50 is provided on the telescope main body 10. In this embodiment, a central focusing knob 50 is provided on the connecting member between the two lens barrels 20, and the central focusing knob 50 is rotatable around the axis for focusing the eyepiece 30. In other embodiments, if the telescope is a single-barrel telescope, a focusing knob may be disposed on the outer surface of the barrel to control the focal length of the telescope through manual adjustment.

Furthermore, the lens barrels are all provided with adjustable annular eyepiece focusing rings 70, which are used for enabling the telescope to adapt to the visual difference of two eyes and obtaining clear visual field.

As shown in fig. 2, the antibacterial lens 60 includes an optical glass 603, an optical antiglare film 602, and an antibacterial film 601 that suppresses bacterial growth, the antibacterial film 601 being provided on a side of the optical antiglare film 602 that faces away from the optical glass 603. An optical antireflection film 604 is further arranged on one side of the optical glass 603 facing the inner cavity of the lens barrel 20 and/or between the optical glass 603 and the optical antiglare film 602. In this embodiment, an optical antireflection film 604 is disposed on a side of the optical glass 603 facing the inner cavity of the lens barrel 20. In other embodiments, in addition to disposing the optical antireflection film 604 on the side of the optical glass 603 facing the inner cavity of the lens barrel 20, an optical antireflection film 604 may be disposed between the optical glass 603 and the optical antiglare film 602; or an optical antireflection film 604 is provided between the optical glass 603 and the optical antiglare film 602.

The optical glass in the embodiment is colorless optical glass which has the characteristics of high transmission in a visible region, no selective absorption, coloring and the like.

The optical anti-dazzle film can prevent light from diffuse reflection, is beneficial to keeping information on a screen clear and visible, and can protect two eyes. The optical anti-dazzle film provides good visibility for people by reducing reflection and glare, and has the functions of preventing ultraviolet rays and filtering out sun glare.

The optical antireflection film has the function of increasing the light incoming quantity. The optical energy reflection loss of the telescope is very serious, in order to reduce the reflection loss of light on the surface of an optical element, a layer of film can be plated on the surface of the telescope, the energy of reflected light can be reduced by utilizing the interference cancellation of the film, and as much energy as possible is transmitted out through the light.

Furthermore, the optical antireflection film is coated with a single antireflection film on at least one optical surface of the optical glass.

Further, as shown in fig. 3, the antibacterial film 601 includes an antibacterial layer 6001, and the antibacterial layer 6001 includes a double ion having antibacterial properties, and the double ion is a silver ion and a copper ion. The double ions in the antibacterial layer 6001 contact with bacteria attached to the surface of the antibacterial layer, and the double ions contact with the bacteria to destroy enzyme proteins, so that the bacteria are broken and die, and the antibacterial effect is achieved.

Silver ions have the advantages of safety, broad-spectrum long-acting property, no drug resistance and the like, silver is regarded as the safest sterilizing agent, and silver-containing medicaments can also be used for treating human diseases. The general antibiotics can only act on 6 germs on average, but the silver ions can kill more than 650 germs. Meanwhile, due to the strong reducibility, the antibacterial agent can perform an antibacterial process repeatedly. Common antibiotics easily cause bacterial drug resistance, and silver ions achieve the bacteriostatic effect through the action of metal ions and the photocatalysis, and cannot generate drug resistance on bacteria. Therefore, the antibacterial lens in the embodiment is prepared by adopting an ion replacement process, and the surface of the lens glass is implanted with the double ions, and the silver ions in the double ions have antibacterial performance. Therefore, the antibacterial lens can effectively inhibit the breeding of harmful bacteria such as algae, fungi, mould and the like. Different from common coated or filmed antibacterial glass, the double-ion replacement process ensures that the antibacterial layer does not fall off due to use, and the antibacterial performance is broad-spectrum and long-acting.

The utility model also constructs an antibacterial lens for a telescope, which is characterized in that the antibacterial lens comprises optical glass 603, an optical anti-dazzle film 602 and an antibacterial film 601 for inhibiting the breeding of bacteria; the antibacterial film 601 is arranged on the side of the optical anti-glare film 602 away from the optical glass 603; the antibacterial film 601 comprises an antibacterial layer 6001, wherein the antibacterial layer 6001 comprises antibacterial double ions which are silver ions and copper ions; an optical antireflection film 604 is further arranged on one side of the optical glass and/or between the optical glass 603 and the optical antiglare film 602. In this embodiment, an optical antireflection film 604 is disposed on a side of the optical glass 603 facing the inner cavity of the lens barrel 20. In other embodiments, in addition to disposing the optical antireflection film 604 on the side of the optical glass 603 facing the inner cavity of the lens barrel 20, an optical antireflection film 604 may be disposed between the optical glass 603 and the optical antiglare film 602; or an optical antireflection film 604 is provided between the optical glass 603 and the optical antiglare film 602.

Furthermore, the anti-reflection film with a single layer or multiple layers is plated on at least one optical surface of the anti-reflection lens, so that stray light of the system is reduced or eliminated, and the anti-reflection film with a larger bandwidth is obtained.

The utility model provides an antibiotic lens have wearability, high temperature resistance good, and antibiotic coverage is extensive, does not have advantages such as the phenomenon of becoming yellow, as shown in the following table, table 1 is the comparison table of antibiotic lens performance.
