Hot Mirrors
Hot mirrors are heat-reflecting mirrors that are designed to work as a shortpass edge filter by transmitting visible wavelengths @AOI 0°, while reflecting NIR, heat-generating wavelengths.

Infrared (IR) Longpass Filters
In infrared optical systems, filters play a critical role in precisely controlling the passage of light at specific wavelengths to optimize imaging quality or signal detection. An infrared Longpass filter is an optical element that allows the transmission of long-wave infrared light (usually light with a wavelength greater than a certain cutoff value, such as 5μm, 8μm, or 10μm) while blocking short-wave radiation. These filters are widely used in thermal imaging, gas detection, military reconnaissance, industrial monitoring and scientific research.

IR Cut Filters
Shortpass Filters, also known as Shortpass Edge Filters, are used to transmit wavelengths shorter than the cut-off wavelength of the filter.

IR Cut Filters
An infrared cut-off filter (IR Cut Filter) is an optical element that is mainly used to block infrared light (wavelength usually greater than 700nm) and allow visible light (about 400-700nm) to pass through. It is widely used in modern imaging systems, especially in digital cameras, smartphone cameras, security surveillance and other areas of critical importance.

LiF Windows
Lithium fluoride is a tetragonal crystal system, the crystal growth can be single polycrystalline blocks or directional growth of single crystals. Therefore, there is a difference between monocrystalline and polycrystalline lithium fluoride. Polycrystalline lithium fluoride is mostly used as protective windows; monocrystalline lithium fluoride is suitable for lenses, prisms and observation windows.
