The OPB-15S01-1-5 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of optical systems. This window is rectangular in shape, with dimensions of 15 x 15 mm, and has a thickness of 1 mm.
The window is made from N-BK7, a type of borosilicate glass that is known for its excellent optical properties. This material is often used in high-precision optical applications due to its low coefficient of thermal expansion and its high resistance to thermal shock. The refractive index of N-BK7 at 588 nm is 1.5168.
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 the addition of a coating could interfere with the performance of the system.
