86-680 12.5 mm Dia. Dichroic Shortpass Filter; t=1.05mm 1150nm

The 86-680 is a Dichroic Shortpass Filter, 12.5 mm in diameter and 1.05 mm thick, available from Edmund Optics. This filter is designed to transmit light with wavelengths shorter than 1150nm, while blocking or reflecting longer wavelengths.

The filter's coating, denoted as 'edm 86-680' on both the front and back surfaces, is specifically designed to provide this shortpass functionality. The filter's geometry, with a diameter of 12.5 mm and a thickness of 1.05 mm, makes it suitable for a wide range of optical applications.

The filter's physical data includes a cut-on wavelength of 0 nm and a cut-off wavelength of 1150 nm. This means that it allows all wavelengths shorter than 1150 nm to pass through, while blocking or reflecting wavelengths longer than 1150 nm.

The filter is shaped as a thin lens, which can be beneficial in certain optical systems where a flat filter might introduce unwanted reflections or aberrations. The catalog number for this filter is 86-680, and it can be found on the Edmund Optics website, where it is currently in stock.
