We Offer Different Types of Optical Filters
RAW MATERIALS SUPPLY
Optical Bandpass Filter
Optical bandpass filters are essential components in various optical systems, designed to transmit a specific range of wavelengths while blocking all others. They are widely used in applications such as biotechnology, machine vision, laser line separation, and fluorescence.
Optical Low Pass Filter
An optical low pass filter (OLPF), also known as an anti-aliasing filter or blur filter, is a crucial component in digital imaging systems. Its primary function is to minimize visual artifacts such as moiré patterns and aliasing, which can occur when fine details in a subject exceed the resolution of the camera sensor.
Optical Notch Filter
Optical notch filters, also referred to as band-stop or band-rejection filters, are specialized optical components designed to selectively block specific wavelengths of light while allowing a broad range of other wavelengths to pass through with minimal loss. This functionality is essential in various applications where precise spectral control is required.
Dichronic Filters
Dichroic filters, also known as dichroic mirrors or thin-film filters, are specialized optical components designed to selectively transmit light of specific wavelengths while reflecting others. These filters operate based on the principle of thin-film interference, where multiple layers of dielectric materials are deposited to create a filter that can control light transmission and reflection effectively.
Long Pass Optical Filter
UV shortpass filters are optical devices that allow ultraviolet (UV) light to pass through while blocking longer wavelengths, including visible and infrared light. These filters are essential in various applications where the isolation of UV light is necessary for optimal performance.
UV Shortpass Filters
Long pass optical filters, also known as long wavepass filters, are designed to transmit light with wavelengths longer than a specified cutoff while blocking shorter wavelengths. This selective transmission is crucial in various applications, including fluorescence microscopy, spectroscopy, and laser systems.
Material and specification of optical filter
- BOROFLOAT 33
As a low expansion, high stability glass material, BOROFLOAT 33 is ideal for use in filters requiring precise optical control. Its coefficient of thermal expansion is small, which can effectively avoid deformation caused by temperature change and ensure optical performance. - quartz
Quartz filters have excellent light transmission properties and are especially suitable for equipment that requires long working hours or use in extreme environments. Its optical transparency and chemical stability make it an ideal filter material for high-end optical instruments. - B270
B270 is a high-quality optical glass that is widely used in optical devices requiring high mechanical strength and temperature resistance. It has excellent formability and high precision machining ability.
Application field
Security and identification technology
Optical filters have become an indispensable part of fingerprint recognition devices, palm print recognition devices, iris recognition devices and other devices. By selecting the appropriate filter, the accuracy and efficiency of optical recognition can be significantly improved, ensuring the stability of the recognition system under different light conditions.
Medical instrument
We supply filters for many medical companies. In bioanalyzers and biometrics, filters ensure that the light signals received by sensors are accurate and compliant. For example, filters in bioanalyzers are able to accurately select specific wavelengths of light for medical tests such as blood oxygen levels, cell analysis, and so on.
Laser technology and measurement
The application of laser technology covers all aspects from laser cutting to laser measuring instruments. Laser Windows and infrared filters play a vital role in these technologies, effectively protecting operators and equipment from unnecessary light interference and improving the efficiency of the instrument. In the field of laser measurement, the filter also optimizes the quality of light and ensures accurate measurement.
