69-184 12.5 mm Dia. Dichroic Shortpass Filter; t=1.05mm 800nm

The 69-184 is a Dichroic Shortpass Filter, 12.5 mm in diameter and 1.05mm thick, available from Edmund Optics. This filter is designed to transmit light with wavelengths shorter than 800nm, while reflecting or absorbing longer wavelengths.

The filter's coating, denoted as 'edm 69-184' on both the front and back surfaces, is specifically designed to achieve this wavelength selectivity. The cut-on wavelength is 0nm, indicating that all wavelengths shorter than the cut-off are transmitted. The cut-off wavelength is 800nm, beyond which the filter begins to block or reflect light.

This filter is circular in shape and is categorized as a Thin Lens, suggesting a flat, thin profile. It is made from UVFS Mal-1965, a material known for its optical properties. The filter's dimensions make it suitable for a wide range of applications, particularly where compactness and light weight are important factors.

The filter's current status is 'in stock', according to the vendor's website, and it is available for immediate purchase.
