Frequently Asked Questions

Optical filters are used to selectively transmit or block certain wavelengths of light in optical systems. They are commonly used in research, industrial, and scientific fields to control the spectral content of light sources and to improve signal-to-noise ratios in imaging and sensing applications.

Some common types of optical filters include bandpass filters, longpass filters, shortpass filters, neutral density filters, dichroic filters, fluorescence filters, and color filters. Bandpass filters transmit a narrow range of wavelengths centered around a specific wavelength, while longpass filters transmit longer wavelengths and shortpass filters transmit shorter wavelengths. Neutral density filters attenuate light without affecting its spectral content, while dichroic filters selectively reflect or transmit certain wavelengths of light. Fluorescence filters are used to selectively excite fluorescent molecules, while color filters transmit only certain colors of light.

Choosing the right optical filter depends on factors such as the desired spectral range, bandwidth, transmission characteristics, and optical power handling capabilities. Consult with an optics expert or manufacturer to ensure that you choose the right filters for your application.

Yes, optical filters can be used in combination with other optical components such as lenses, mirrors, and prisms. They are often used in conjunction with these components to improve the performance of optical systems and to achieve specific experimental or imaging goals.

Narrowband filters are designed to transmit or block a narrow range of wavelengths, while broadband filters are designed to transmit or block a wider range of wavelengths. The choice of narrowband or broadband filters depends on the specific requirements of your application, including the spectral range of your light source and the desired transmission characteristics of the filter.

Our filters category offers a wide selection of optical filters designed for precise wavelength control and high optical performance. Whether you need bandpass filters, longpass filters, shortpass filters, neutral density filters, or other types of optical filters, we have you covered. Our filters are suitable for a variety of applications in research, industrial, and scientific fields. Explore our selection and find the right filters for your needs.

The first useful semiconductor laser was made by R.N. Hall in 1962 which was composed of GaAs materials that emitted in near infrared at 0.8 µm. The semiconductor laser is similar to transistor, has the appearance of a LED but the output beam has the characteristics of a laser. The application that was the main driving force in the development of semiconductor lasers was in the field of long distance communications but at this moment the use of this laser in compact disc players constitutes their largest single market. Using semiconductor laser gives an advantage of low power consumption requirements.
