G344212000 20 x 30 mm N-BK7 Broadband 50:50 (R:T) Plate Beamsplitter; t=2.5mm IR 1200-1700nm

This beamsplitter, model G344212000, is a high-quality optical component designed for broadband applications in the infrared spectrum. Manufactured by Qioptiq Photonics, it boasts a rectangular shape with dimensions of 20 x 30 mm and a thickness of 2.5 mm.

The beamsplitter is made from N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and wide transparency range. This material is particularly suitable for beamsplitters due to its low auto-fluorescence and high damage threshold.

The beamsplitter features a broadband 50:50 (R:T) coating, which means it reflects 50% of the incident light and transmits the remaining 50%. The coating is applied to both the front and back surfaces of the beamsplitter. The front surface coating is 'qio bbbs 50 tbpir 45', while the back surface coating is 'qio bbar arb2irnbk7'. These coatings ensure high performance and durability across the beamsplitter's operational wavelength range of 1200-1700nm.

The beamsplitter's physical data indicates a reflection of 0.5 and a transmission of 0.5, consistent with its 50:50 design. This beamsplitter is an excellent choice for applications that require precise beam splitting in the infrared spectrum.
