This is the HO-WCB-10-3, a 10 mm diameter N-BK7 circular flat window with a thickness of 5 mm, uncoated. The window is a product of Holmarc Opto-Mechatronics, a renowned vendor in the optical industry.
The window is designed in a flat shape, which is ideal for applications that require minimal optical distortion. The base shape of the window is circular, making it suitable for applications where a circular aperture is required.
The window is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This type of glass, also known as BK7, is known for its low dispersion and high transmission in the visible spectrum, making it an ideal choice for applications that require high optical quality.
The window has a thickness of 5 mm, providing sufficient mechanical strength while maintaining minimal optical distortion. The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be beneficial for applications where coatings may interfere with the optical path.
The window is designed for a wavelength of 632.8 nm, which is in the red part of the visible spectrum. This makes it suitable for applications that use red light, such as certain types of laser systems.
