Applied to the optical display field.
Color filters are applied to the light display area. A color filter is a light filter that reflects other undesirable colors off by bands while accurately selecting the desired range through small bands of light. Color filters are typically placed in front of a light source, allowing the human eye to receive saturated colors of light. There are infrared filters, green, blue, and so on.
Neutral density filter
The attenuation of fixed neutral density filters can be made uniform across a wide spectral range, coated with a durable metal film, and can be used in fields such as natural light and lasers.
Neutral density filter
Circular gradient neutral density filters (abbreviated as circular gradient density sheets) can achieve linear attenuation of light intensity by rotating the filter, allowing for precise adjustment of light energy in a circular linear direction while maintaining a neutral spectral energy distribution. This enables control and adjustment of energy under the premise of maintaining neutrality. These filters can be applied in fields such as natural light and lasers. By combining two filters and rotating them in opposite directions, a fixed density attenuation effect can be achieved over a limited wide range. The product size options range from 25 mm to 100 mm, and the spectral range is from 250 nm to 2500 nm. Customization of special sizes, densities, and wavelength density sheets is available. Please contact us for more details.
Neutral density filter
The circular step neutral density filter (abbreviated as circular step density sheet) attenuates the intensity of light based on the discrete number of steps within the filter area. The light density within each discrete area is a fixed value. This filter can be applied in fields such as natural light and lasers. The outer diameter of the filter can be selected from 25 mm to 100 mm. The optional usable spectral range is from 250 nm to 2500 nm. Special sizes, densities, and concentrations of sheet wavelengths can be customized.
Neutral density filter
Radial gradient neutral density filter (abbreviated as radial gradient density sheet) can attenuate the trend of light intensity using a Gaussian function (or other functions) and can be used in fields such as natural light and lasers. The optional usable spectral range is from 250nm to 2500nm.

High-density hard membrane, long service life.
Our high-performance narrowband and broadband UV bandpass filters have a spectral range of 200nm to 380nm. The ultraviolet bandpass filters are manufactured using Ion Beam Sub-Deposition (IAD) and Plasma-Assisted Deposition (PIAD). The filter films are made with high-density hard coatings, ensuring a long lifespan.
Visible bandpass filter
Our company offers a variety of high-performance narrowband and broadband visible bandpass filters. The spectral range is from 380nm to 700nm. The half-peak width (FWHM) of the bandpass filters ranges from 4nm to 100nm. The cut background from X-rays to the near-infrared region is higher than OD4.
High transmittance through the band, wide bandwidth cutoff, membrane dense stability.
This type of long-wave pass filter is suitable for beauty equipment, as it can block light in the short-wave area of the skin while maximizing the useful area to improve the efficiency of light energy utilization. This type of filter is manufactured using membrane technology and is characterized by high transmission in the passband suitable for light systems, wide-band cutoff, and membrane density stability, ensuring that it does not get damaged by strong light sources in beauty devices.
Ultra-wide spectral transmission with a high cut rate in the near-infrared region.
The IR cut filter (IR BLOCK FILTER) has a very wide spectral transmission (380nm to 700nm) and a high cut rate in the near-infrared region.
Wavelength gradient filter
Linear Variable Filter (LVF) - has characteristics such as wavelength gradient, channel selection, and stable performance.
Long wave pass / Short wave pass
Our company offers high-quality long-wave and short-wave pass filters, featuring a high cut-off slope between the passband and the cut-off region, with a high cut-off background in the X-ray range at 1200 nm, and an average transmittance of over 90% in the passband region. We provide customized products according to our clients' needs.
Neutral density filter
Strip step gradient neutral density filter (also referred to as strip step density sheet) attenuates light intensity based on the discrete number of steps within the filter area. The light density within each discrete area is a fixed value. This filter can be applied in fields such as natural light and lasers. It includes metal alloy variable density sheets and low reflection variable density sheets (GND), with an optional spectral range of 250nm to 2500nm. Custom sizes, densities, and concentrations of sheet wavelengths can be tailored.
