Precision Optical Interference Filter. This is New Old Stock that is left over from manufacture for a large biomedical instrument manufacturer This filter is specifically for attenuation the primary laser output from an Argon laser, at both its primary and 2nd Harmonic output. The filter allows over 75% of a wide spectral band to the red of the 532 2nd Harmonic to be transmitted, yet attenuates the primary wavelengths to a level of 1e10-6 minimum. A second stop bands coincides with 632 HeNe output, and a third stop band at 785nm, as well as a band that takes the 1064 primary out to a level of 1e10-6 The filter can be used to view fluorescence excited by either 532, 633, 785 0r 1064nm Laser output. Other applications include observation windows to see secondary optical images, in the field of view that is illuminated by the bright laser source. The Filter Specifications follow: Rejection Wavelength, 532, 633, 785, and 1064nm, Rejection Band Width 25 to 50nm, Rejection level 1e10-6, Size 25 mm round. Optical Density and transmission curve supplied. (Optical filter laser rejection 532 & 1064NM 25MM omega was posted and is owned by: Jeanine Holman) |
