86-690 25 mm Dia. Dichroic Shortpass Filter; t=1.05mm 1050nm
The 86-690 is a Dichroic Filter with a 25 mm diameter and a thickness of 1.05mm, designed for use with a central wavelength of 588nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is designed with a dichroic coating on both the front and back surfaces, specifically the EDM 86-678 coating. This coating is responsible for the filter's shortpass characteristics, allowing light of shorter wavelengths to pass through while reflecting or absorbing longer wavelengths. The cut-on wavelength for this filter is 0nm, and the cut-off wavelength is 1050nm.
The filter is shaped as a thin lens, making it suitable for use in a variety of optical systems. The circular geometry of the filter, with a diameter of 25mm, adds to its versatility. The material ID for this filter is UVFS MAL-1965, although further details about the material composition are not provided in the item data.
