HO-WCBB-20-3 20 mm Dia. N-BK7 Circular Flat Window; t=5mm BBAR 400-700nm

Holmarc Opto-Mechatronics offers the HO-WCBB-20-3, a circular flat window made of N-BK7 glass with a diameter of 20 mm and a thickness of 5 mm. This window is designed for use in optical systems where high transmission and minimal distortion are required.

The window features a broadband anti-reflection (BBAR) coating on both the front and back surfaces, optimized for the 400-700 nm range. This coating significantly reduces reflection losses, enhancing the overall transmission of the window. The BBAR coating is applied using Holmarc's hol bbbar 0 aoi process, ensuring high-quality, durable coatings.

The window is shaped as a thin lens, making it suitable for use in various optical applications. The geometry specifications, including the diameter and thickness, are carefully controlled to ensure precise optical performance. The N-BK7 material, a common choice for optical elements, provides excellent optical quality and is highly resistant to thermal shock and chemical attack.
