Sell Interference Filter

Description

Interference filter is precision optical filter basis on the interfering principle of optical film. Optical products can be coated with reflection reducing coating(MgF2 )&#****9;Broad-band reflection reducing coating(&#**5;**0&#****4;***0nm)&#****9;reflective coating :aluminium reflection(reflectivity>*0%)&#****9;dielectric layer (reflectivity>*9.5%)&#****9;beam splitter(any T/R)&#****9;narrow-band filter(as below). It attained the characters of diversified action spectrum according to designing and changing structure and optical parameter of film, it is used for control, adjust and change the transmission, reflection, absorbing, polarization and situation of phase. Narrowband filter for medical biomedical instrument applies in biomedical instrument, urinalysis and other medical biomedical analytical instruments. The product have the high SNR, background control OD5&#****4;OD6, (T=***5&#****4;***6), to ensure the accurate measurement of instrument within the scope of absorbency A=2&#****4;A=4.
