G344231000 22.4 mm Dia. N-BK7 Broadband 50:50 (R:T) Plate Beamsplitter; t=3mm IR 1200-1700nm

This is a 22.4 mm diameter Beam Splitter Plate, specifically designed for use in the infrared spectrum, with a wavelength of 1550nm. The beamsplitter is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.

The beamsplitter is made of N-BK7, a high-quality borosilicate glass, which is known for its excellent optical properties and durability. The beamsplitter has a thickness of 3mm, providing a robust and stable platform for optical applications.

The beamsplitter features a broadband 50:50 (R:T) coating, which is applied to both the front and back surfaces. This coating ensures a balanced 50% reflection and 50% transmission ratio for the incident light, making it ideal for applications that require equal distribution of light.

The front surface of the beamsplitter is coated with "qio bbbs 50 tbpir 45", a proprietary coating from Qioptiq Photonics. This coating is designed for broadband reflection, ensuring high performance across a wide range of wavelengths. The back surface is coated with "qio bbar arb2irnbk7", a proprietary anti-reflection coating that minimizes unwanted reflections and improves transmission.

The beamsplitter is designed in a thin lens shape, providing a compact and lightweight solution for optical systems. Despite its thin profile, the beamsplitter offers robust performance and high optical quality.
