OPB-30C03-1-5 30 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-30C03-1-5 is a 30 mm diameter N-BK7 round optical parallel flat window with a thickness of 3 mm, uncoated and sourced from OptoSigma. This window is designed for use in optical systems where a flat, transparent surface is required to maintain the optical path without introducing any additional optical properties.

The window is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties and wide transmission range. N-BK7, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for various optical applications.

The window's thin lens shape allows it to be easily integrated into optical systems without introducing significant spherical aberration or other optical distortions. The uncoated surface ensures high transmission at the specified wavelength of 588 nm but may have higher reflectivity compared to coated alternatives.

This OptoSigma window is available for purchase directly from their website, and the link provided indicates that it is currently in stock. With its high-quality materials, precision manufacturing, and versatile applications, the OPB-30C03-1-5 is an excellent choice for researchers and engineers seeking a reliable and efficient flat optical window.
