39-300 25.0 x 25.0 mm UVFS Protective Flat Window; t=2 mm NIR II 750-1550nm

The 39-300 is a 25.0 x 25.0 mm UVFS Protective Flat Window, designed with a thickness of 2 mm, specifically engineered for use in the Near-Infrared II (NIR II) spectrum, covering the wavelength range of 750-1550nm. This window is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.

The window is rectangular in shape, with a base shape that is flat, making it ideal for applications that require a stable, unaltered optical path. The window's geometry is defined by its width (25 mm), length (25 mm), and thickness (2 mm), providing a substantial yet manageable optical element for various setups.

The window is constructed from UVFS material, specifically identified as UVFS Mal- 1965, a material known for its optical properties and durability. This material is often used in applications that require high transmission and excellent environmental stability.

The 39-300 window features a coating on both the front and back surfaces. The front surface is coated with the EDM NIR-II STD CURVE, a coating specifically designed for use in the NIR II spectrum. Similarly, the back surface also features the EDM NIR-II STD CURVE coating, ensuring consistent performance and protection from environmental factors on both sides of the window.

The window is shaped as a thin lens, suggesting its potential use in applications that require minimal optical distortion and a clear, undeviated optical path. This window is a versatile and reliable option for those requiring a high-performance optical element in the NIR II spectrum.
