590FDL12 12.5 mm Dia. Longpass Dichroic Filter 590nm

The 590FDL12 is a Dichroic Filter, specifically a Longpass Filter with a 590nm cut-on wavelength, sourced from Knight Optical. This filter is designed with a circular geometry, featuring a 12.5mm diameter and a thickness of 1.1mm. The material used in the construction of this filter is N-BK7 Schott, a well-regarded optical glass due to its excellent homogeneity, low auto-fluorescence, and high damage threshold.

The filter's primary function is to reflect wavelengths shorter than 590nm while transmitting wavelengths longer than 590nm. This is facilitated by the dichroic coating on both the front and back surfaces, denoted as 'kni 590fdl-0'. The cut-on wavelength is precisely set at 590nm, ensuring a sharp transition between the reflected and transmitted wavelengths.
