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
Negative filters can reduce the certain laser wavelengths such as 488nm and 561nm, not only has protective effects on the eyes, but can identify the spectral characteristics of different colors objects more clearly. The negative filter has a small half bandwidth and the accurate wavelength positioning.

Band-pass Filter

    The band-pass 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 work area is generally in ultraviolet light area, near infrared area and far infrared area.
    Product Application
Mainly used in the field of biochemical, medical, image recognition, detection sensors and laser systems.

Cut-off Filter

The cut-off filters are an optical device which only permits the transmission of radiation of wavelengths that are longer than or shorter than a specified wavelength. CNI can offer different kinds of cut-off filters upon your requests.

Long Pass Filters, Ravg 99% from UV to 500 nm, Tavg 95% from 530nm to 1200nm

Short Pass Filters, Ravg99% from 700 to 900nm, Tavg 95% from 400nm to 680nm, other specs are available on requests.
