49-437 25 mm Dia. N-BK7 Wedge Prism; t=3 mm VIS-NIR 400-1000nm
This is a 25 mm diameter N-BK7 Wedge Prism, with a thickness of 3 mm, specifically designed for the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The prism is sourced from the reputable vendor, Edmund Optics.
The prism's base shape is circular, and it features a wedge angle of approximately 0.016872097879029185 radians. This angle, combined with the prism's N-BK7 material, ensures efficient light refraction and minimal optical loss.
The N-BK7, or Schott glass, is a popular choice in optical systems due to its excellent optical properties, including low auto-fluorescence and a high Abbe number. This makes the prism suitable for a wide range of applications, from imaging and beam shaping to spectroscopy and interferometry.
The prism's surfaces are coated with the EDM VIS-NIR 0SP200-2000 coating on both the front and back. This anti-reflection coating is designed to minimize surface reflections and increase transmission in the VIS-NIR range. The coating ensures optimal performance and durability, reducing the need for frequent maintenance or replacement.
