This beamsplitter, offered by Edmund Optics, is a circular plate with a diameter of 12.5 mm and a thickness of 3 mm. It is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 700 and 1100 nm.
The beamsplitter is made of 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 applications in the NIR region.
The beamsplitter features a 40:60 (R:T) coating on its front surface, denoted as edm 68-382. This coating is designed to reflect 40% of the incident light and transmit 60%. This ratio is maintained for the specified wavelength range, making this beamsplitter ideal for applications that require precise control over light distribution.
The beamsplitter is shaped as a thin lens, which minimizes optical aberrations and ensures high-quality performance. It is currently in stock and available for immediate purchase, as indicated by its weblink status.
