14-017 25.2 x 35.6 mm Low GDD Dichroic Shortpass Ultrafast Filter 900nm

The 14-017 is a 25.2 x 35.6 mm Low GDD Dichroic Shortpass Ultrafast Filter, specifically designed for use at the 900nm wavelength. This filter is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase through their website.

The filter is a Dichroic type, which means it selectively reflects or transmits light based on its wavelength. In this case, it is designed to pass light with wavelengths shorter than 900nm while reflecting light with longer wavelengths. This makes it ideal for applications where short wavelength light needs to be isolated or preserved.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It has a rectangular base shape, with a width of 25.2mm and a height of 35.6mm, making it suitable for use in a variety of optical systems. The filter has a thickness of 1.05mm, which is relatively thin, reducing the likelihood of it causing optical aberrations.

The physical data of the filter is also noteworthy. It has a cut-on wavelength of 0nm, meaning it begins transmitting light immediately, and a cut-off wavelength of 900nm, after which it begins to reflect light. This makes it a shortpass filter, as it passes short wavelengths and reflects long ones.

The filter is coated on both the front and back with EDM 14-006, a coating that likely enhances its optical properties. The shape of the filter is thin lens, suggesting it may have some focusing or diverging properties.
