14-004 25 mm Dia. Low GDD Dichroic Shortpass Ultrafast Filter 800nm

The 14-004 is a 25 mm diameter Low GDD Dichroic Shortpass Ultrafast Filter, specifically designed for use at the 800nm 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 below 800nm while reflecting light above this wavelength. This makes it ideal for applications where short-wavelength light needs to be isolated or preserved.

The filter has a base shape of a circle, a common form factor for optical elements due to its symmetry and ease of integration into various systems. It is made from UVFS Mal-1965, a material with specific optical properties that make it suitable for use in ultrafast applications.

The filter has a diameter of 25mm and a thickness of 1.05mm, making it a thin lens. This thinness can be beneficial in applications where space is at a premium or where minimal interference with light paths is desired.

The filter's coating is applied to both the front and back surfaces. The front coating is EDm 14-004, and the back coating is also EDm 14-004. These coatings play a crucial role in the filter's performance, ensuring the specified wavelength cut-on and cut-off points are met.
