Bandpass filters are commonly matched or combined with other filters to optimize performance in your specific application. Our enhanced OEM designs combine multiple coatings onto the same optic to improve the device’s size, weight and performance. Some of these complementary filter types include:

Unlike absorbent polymer or colored-glass gels, our UV bandpass filters consist of thin films and are virtually absorption-free, providing high-contrast spectral bands, outstanding transmission and lifetime performance. We design our filters for either narrow or wide bandwidths. They also have sharp-edge differentials between the wavelength reflection bands and high transmission bandpasses steeper than polymer or colored-glass gels.

Optical Filter Shop’s UV bandpass filters can be shipped in as little as one day if they’re in stock. Our inventory is also perfect for quick prototyping, and the OEM prices are competitive for volume production. If you need to try a specific type of filter for experimentation, we have a standard range of filter samples ready to ship.

The polarization of light can be determined using a polarizing filter or polarimeter. A polarizing filter is a special type of optical filter that only allows light waves oscillating in a specific direction to pass through, while blocking all other orientations. A polarimeter measures the angle at which light is polarized and can determine whether the light is polarized or unpolarized.

Optical Filter Shop supplies custom OEM filters to match the specific angle and wavelength requirements engineered to your exact specifications. In addition to customized filter coatings, we deliver optics to fit your application in specific shapes, sizes and substrates.

In many cases, an optimal OEM design integrates multiple coatings onto the same optic to improve the device’s performance, size and weight. The customization process can be as simple as choosing the type of filter you need, the shape and the required dimensions.

No, laser light can be either polarized or unpolarized, depending on the type of laser and the materials used to create it. Some lasers, such as gas and semiconductor lasers, produce polarized light, while others, such as dye and solid-state lasers, produce unpolarized light. The polarization of laser light can also be controlled using specialized optical components.

Laser light is produced when a large number of photons (light particles) are generated in a process called stimulated emission. This process involves exciting atoms or molecules to a higher energy state, causing them to release photons that are all in phase and have the same wavelength and direction of oscillation. This results in a concentrated beam of light with very specific properties, such as being highly monochromatic (having a single wavelength) and highly directional.

Optical Filter Shop’s ultraviolet (UV) bandpass filters transmit visible spectral bands while masking outside signals at lower and higher wavelengths. Our bandpass filters have multiple edges to transmit wavelengths defined by a full-width half-max (FWHM) bandwidth and a nominal center wavelength (CWL) while also reflecting shorter and longer wavelengths. Also known as interference or thin-film filters, our bandpass filters utilize multi-layer hard coatings that provide durable performance without aging or fading in high output luminaires.

Polarization of light refers to the direction in which the electric field of the light waves oscillates. This direction can be either perpendicular or parallel to the direction of propagation of the light wave. In unpolarized light, the electric field oscillates in all possible directions, while in polarized light, the electric field oscillates in a specific direction.

Our UV bandpass optical filters’ 200-400nm range is below human vision and within the responsitivity of UV-optimized silicon detectors. They provide a wide array of advantages in both the scientific and industrial sectors. Several examples are:

Polarized laser light has a wide range of applications in various fields such as telecommunications, medicine, and research. It is used in optical storage devices, fiber optics, and laser surgery. It is also used in experiments and studies that require the manipulation of light, such as in studying the properties of materials and in creating holograms.
