HO-WRB-20-3 20 x 35 mm N-BK7 Flat Window; t=5mm Uncoated
This is a rectangular flat window, type HO-WRB-20-3, manufactured by Holmarc Opto-Mechatronics. The window measures 20 x 35 mm and has a thickness of 5mm. It is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and low coefficient of thermal expansion.
The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where the natural properties of the glass are desired, or where cost considerations are a factor. However, it should be noted that uncoated windows can have higher reflectivity, which may need to be taken into account in the design of the optical system.
The window is designed for use at a wavelength of 632.8 nm, making it suitable for a wide range of applications in the visible spectrum. It is available for purchase directly from the Holmarc Opto-Mechatronics website, where more detailed specifications and technical data can be found.
