The spectroscope is a special optical processing substrate, which is coated with high-precision optical medium to ensure no ghosting, high smoothness, imaging without black spots,
Color filter concept The filter working in the visible light region in the spectral range is called color glass filter. It can reflect or transmit
In the optical lens of optical elements, every point on the object plane in the effective field of view will form a clear image point
When manufacturing filters, we not only use conventional physical vapor deposition (PVD) multilayer coating, but also combine precise packaging technology to ensure environmental stability, and
All optical elements are precise, especially optical filters, which are the core components of all optical application systems. Once problems occur, the whole optical system
The phase-length interference condition of Fabry-Perot cavity can effectively penetrate the light in a small range on both sides of the central wavelength and the
The optical coating is composed of thin film layers, which will produce interference effect to change the transmission or reflection performance of the optical system.
In daily life, handicrafts and products can be seen everywhere with unique appearance and patterns. Materials include steel, wood, plastic, glass, etc. These pleasing products
The beam-combining mirror is used to combine the light of two wavelengths into a light path through transmission and reflection. In laser processing, it is
In the common laser microscope, the wide field light source and the laser light source have different requirements for the filter, which are mainly shown
