Changchun Hengyi Optics Co., Ltd can manufacture various optical filters, such as Color Separation Filters,



Neutral Density Filters, Short/long wave Pass Filters, Bandpass Filters, etc.

Color Separation Filters

Color separation filters, are used in optical systems where the incident light needs to be split into two or more wavelength regions or 'colors' with a high degree of efficiency.

Custom products

Our ability can be up to:

Material: Optical crown glass(BK7A) or other materials

Diameter: 2-300mm

Diameter Tolerance: -0.10mm

Minimal Thickness:0.5mm

Parallelism: 1 arc minutes

Flatness: λ/10 at 632.8nm

Surface Quality:20-10 scratch dig

Clear Aperture: 90% of Diameter

Operating Temperature:Up to 200C

Neutral Density Filters

(i)Neutral Density Filters - Absorptive

(ii)Neutral Density Filters - Reflective

The main purpose of using neutral density filters is to reduce the amount of light that can pass through the lens. As a result, if a shutter speed is kept the same, after adding a neutral density filter, a larger aperture must be used to obtain the same exposure. Similarly, if an aperture is kept the same, after adding a neutral density filter, a slower shutter speed must be used to obtain the same exposure.
