These uncoated windows operate within a wavelength range from 2.0 μm to 16.0 μm, exhibiting high transmittance across the entire spectral band. For details, see the transmittance curve. Due to Germanium's broad infrared transmission spectrum, it is highly suitable for infrared laser applications. Germanium's opacity in the visible light spectrum also allows it to function as a long-pass filter, transmitting wavelengths above 2.0 μm.  \n\nThe spectral transmittance of Germanium is highly sensitive to temperature. At an ambient temperature of 100°C, the material's absorption increases significantly, becoming nearly opaque, and at 200°C, it becomes completely opaque.  \n\nSafety Notice: Germanium contains hazardous substances. While operation, wear gloves, a particulate-filtering respirator, chemical safety goggles, and impermeable protective clothing.

This minimizes phase discrepancies between split beams, thereby yielding superior experimental results. Depending on the wavelength range, the substrate materials of these compensators typically feature low refractive index, high uniformity, and low thermal expansion coefficients.  \n\nCurrently, LBTEK offers 45° beam splitter compensators with UV-grade fused silica substrates suitable for the 250 nm–450 nm wavelength range. These are available in two size options: circular (1-inch diameter) and rectangular (25 mm × 36 mm).  \n\nLBTEK's 45° beam splitter compensators deliver excellent performance, efficiently eliminating phase differences between beams. Additionally, LBTEK provides various customization services, including tailored materials, wavelength compatibility, and dimensions\/thickness specifications.
