Filter

 

The filter is a kind of optical elements which to make a specific wavelength of light to pass through, and the other wavelength of light reflection or attenuation. The advantages of the filter having the high transmittance of the peak value, a flat pass band spectrum in a wide wavelength range with excellent cutoff, and the temperature stability is better.


Negative filter

 

The negative filter is a kind of optical elements which to make a specific wavelength of light to pass through, and the other wavelength of light reflection or attenuation. The filter has some characteristics such as a high transmittance and high reflectance. Mainly used in the fluorescence analysis system.

Band-pass filter

 

 

Because of its high capacity and reliability, multi-mode optical fiber coupling laser generally is used for many fields. Because multi-mode fiber has a larger core-size, it supports more than one propagation mode; hence it is limited by modal dispersion.

Cut-off filter


The cut-off filter has a periodic structure constituted by the high refractive index layer and the low refractive index layer alternately. The main products are long-wavelength pass filter and short-wavelength pass filter. The products we can provide have some characteristics, for instance, spectral performance is very stable and long service life.

Neutral density filter

 

Neutral density filter can be used to adjust the light output energy continuously and greatly. The neutral density filters include linear gradient filters, circular gradient filters and fixed density filters.
