Abstract

PURPOSE:To make it possible to reduce the size, while lowering the loss of a beam, by directing overlapping optical interference film filters of band blocking type. CONSTITUTION:The interference film filters F'1 to F'6 for reflecting a wavelength lambdac while allowing the other wavelength to pass therethrough are overlapped in multiple layers such that the respective blocking wavelengthes are indicated at lambda1 to lambda6. If an incident light is irradiated at an inclination, the reflected lights lambda1 to lambda6 from the respective filters can be separately extracted.
