This is a Flat Window type optical element from Holmarc Opto-Mechatronics, measuring 25 x 25 mm in base shape and having a thickness of 6mm. The window is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold.
The window features BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, designed for the wavelength range of 400-700nm. This coating significantly reduces reflection, thereby improving transmission and enhancing the overall performance of the optical system.
The window is designed for use in a variety of applications, including but not limited to, beam shaping, beam splitting, and protection of sensitive optical components. It is available for purchase directly from the Holmarc Opto-Mechatronics website, where you can find more detailed specifications and additional product information.
