46-644 75 x 75 mm 75:25 (R:T) Float Glass Standard Plate Beamsplitter; t=1mm 400-700nm

This 75 x 75 mm Beam Splitter, model 46-644, is a high-quality optical component sourced from Edmund Optics. It is designed with a 75:25 (R:T) split ratio, meaning it reflects 75% of the incident light and transmits 25%. This specific beamsplitter is a thin plate, offering advantages in terms of weight and potential integration into various optical systems.

The beamsplitter is made of soda lime glass, a common material in optical applications due to its excellent transparency and durability. The glass has a thickness of 1mm, providing a good balance between robustness and light transmission. The operating wavelength range for this beamsplitter is 400-700nm, making it suitable for a wide range of applications, including but not limited to, biomedical imaging, machine vision, and optical metrology.

The front surface of the beamsplitter is coated with edm 46-666, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance by ensuring the specified 75:25 split ratio across the operational wavelength range. The back surface is coated with edm mgf2 std curve, another proprietary coating that further optimizes the beamsplitter's performance.

In terms of geometry, this beamsplitter is rectangular, with a width of 75mm and a height of 75mm. This shape is versatile and can be easily integrated into various optical systems. The beamsplitter's physical data indicates a reflection of 0.75 (75%) and a transmission of 0.25 (25%), aligning with its specified 75:25 split ratio.
