Description :

ZET488/640m-TRF is a dual band laser emission filter providing narrow blocking bands at 488nm, 640nm for TIRF application.

Chroma's multiband laser emission filters provide for the widest passbands for fluorescence transmission, with relatively narrow blocking bands, corresponding to the intended laser wavelengths. These particular emission filters are of limited use in non-laser applications due to their narrow attenuation ranges. The essential property of an emission filter in any laser application is adequate attenuation of the laser line(s). For Laser Emission Filters, its most important property is sufficient blocking of the laser line(s) being used.
