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

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

In optical elements, light energy is lost due to the reflection of the element surface. In order to reduce the reflection loss on the surface

Collimator is for point light source, and the so-called point light source, we see more in life, such as: match head lighting, the bulb of
