45-387 N-BK7 Right Angle Prism; 6.25 mm MgF2 Legs/Aluminized on Hypotenuse

The 45-387 N-BK7 Right Angle Prism is a high-quality optical component sourced from Edmund Optics. This prism is made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and wide transparency range. The prism's right-angle design allows for total internal reflection, making it ideal for a variety of applications such as beam folding, image reflection, and light direction.

The prism features 6.25 mm MgF2-coated legs and an aluminized hypotenuse. The MgF2 coating, or Magnesium Fluoride, is a broadband, high-reflectivity coating that provides excellent transmission and low absorption across a wide range of wavelengths. This makes the prism suitable for use in systems operating at the specified wavelength of 587.6 nm.

The hypotenuse of the prism is aluminized, which provides high reflectivity at normal incidence. This coating is particularly useful in applications where high reflectivity is required, such as laser systems or interferometry.

The prism's geometry is another notable feature. With a length of 6.25 mm for each leg and a hypotenuse length of 8.8 mm, this prism is designed for precision and accuracy. The base shape is a volume prism, which is a versatile and widely used prism shape in optical systems.
