Product attribute Material: optical grade glassND attenuation range: OD0.1~OD5Size: customizedWavelength range: 400nm~700nm Content Introduction The UV filter is a piece of transparent glass in front of the lens, which can block scratches and impacts and protect the lens; the ND filter is also called the…
How an Infrared Variable Neutral Density Filter Works The IR VND filter typically consists of two polarizing films or elements with adjustable relative rotation. The filter’s density—and thus the level of light attenuation—can be varied by rotating these polarizing elements relative to each other. In…
A polarizing film is an optical filter that selectively transmits light with a specific polarization while blocking other orientations. This film is designed to either absorb or reflect light waves with certain orientations, thereby creating a polarized output. Polarizing films are widely used in applications…
Product parameters Features Splitting ratio: 40:60 beam splitter distributes the incident light in a ratio of 40% transmission and 60% reflection, which is suitable for occasions where asymmetric distribution of light energy is required.Wide spectral range: This beam splitter can be designed for different spectral…
The SP705 short-wave filter is actually an infrared cutoff filter. Its core function is to block infrared light above 705nm and only transmit visible light. This filter is specially designed to block infrared light above 705nm, effectively suppressing the passage of long-wave light and ensuring…
UV-IR Cut Filter is an optical filter specially designed to block ultraviolet (UV) and infrared (IR) light and only allow visible light to pass through. Its function is to achieve spectral selectivity in a variety of optical systems, thereby improving the quality and accuracy of…
The NBP365 ultra-narrowband filter, with its high precision and high signal-to-noise ratio in the 365nm band, meets the stringent requirements of modern fluorescence detection for sensitivity and reliability. The application of this filter has greatly expanded the technical boundaries in the fields of fluorescence microscopy,…
POCT (Point-of-Care Testing) is a type of small portable diagnostic instrument designed to quickly obtain test results at the sampling site or at the patient’s bedside. The main features of this device include miniaturization, portability, simple operation, no need for a special operating environment, and…
BP532 bandpass filter is a wide-spectrum passband optical element. Since yellow light has a good warm tone and green light has a good performance for green leaf environment, it is very suitable for shooting jungle effects in the early morning. In addition, this product covers…
NBP635 narrowband filter is an optical filter specially designed to have high transmittance at 635nm wavelength. It has a very narrow transmission band and only allows light near 635nm to pass through, which can effectively isolate other wavelengths of light outside the band. This filter…
