HO-RPB-E-5 N-BK7 Right Angle Prism; 5 mm Protected Aluminum on Legs

This is a right angle prism, specifically the HO-RPB-E-5 model from Holmarc Opto-Mechatronics. The prism is made of N-BK7 glass, a type of borosilicate crown glass that is known for its excellent optical properties, including low dispersion and high homogeneity. This particular prism has a Schott glass designation, indicating its high quality and adherence to strict manufacturing standards.

The prism's geometry is cubic, with each side measuring 5 mm. This compact size makes it suitable for a wide range of applications where space is a constraint. The prism's right angle shape allows for total internal reflection, making it ideal for use in beam deflection and beam splitting applications.

The prism is coated with protected aluminum on both the front and right faces. This coating enhances the prism's reflectivity, particularly at the 632.8 nm wavelength, which is commonly used in laser applications. The 'protected' designation means that the aluminum layer is overcoated with a protective layer, which enhances the coating's durability and resistance to environmental factors such as humidity and oxidation.

The HO-RPB-E-5 prism is currently in stock and available for purchase through the Holmarc Opto-Mechatronics website. With its high-quality N-BK7 glass, protective aluminum coating, and compact geometry, this prism is a versatile and reliable choice for various optical applications.
