HARD-COATED NARROWBAND FILTERS
First-surface, hard-coat narrowband filters employ magnetron sputtered, hard-oxide coatings deposited on Borosilicate Glass and do not utilize any absorbing filter glasses, making them suitable for high-temperature applications. provide a steep transition from a high, peak transmission to OD4 blocking. Available at wavelengths from 334nm to 1550nm, including all major laser lines and atomic absorption lines. All filters are mounted in black anodized aluminum rings to provide protection and easy identification.
STANDARD IR BANDPASS FILTERS
In the infrared region of the spectrum, bandpass filters are frequently used for gas analysis applications. Our suppliers offer a standard selection of gas analysis filters at popular wavelengths. They can also produce custom filters at wavelengths up to 14µm. Constructed of durable first-surface dielectric coatings on optical-quality IR-transmitting substrates, these filters will withstand normal cleaning and handling associated with any high-quality optical component.
MOTORIZED FILTER WHEELS
These filter wheels are used for a host of applications, including color CCD photography, fluorescence microscopy, and photometry. Two 4″ dia, wheels are available: one which accepts six 25mm filters, and one which accepts twelve 12.5mm filters.
IMAGE QUALITY METALLIC NEUTRAL DENSITY FILTERS UV-VIS-NIR
Neutral density (ND) filters are useful in a number of applications such as attenuators for broadband spectral sources, partial reflectors for light balancing applications and for use as neutral beamsplitters. Metallic type neutral density filters obtain their optical density. by depositing a metal alloy coating onto a specific type of substrate which is determined by the wavelength region of interest..
BANDPASS FILTERS
There are a number of variations of an optical bandpass filter’s construction, and each has its advantages. offers a variety of options so that you can select the best-suited filter type for your application. If you would like advice from our technical sales staff, please contact us.
Here are 10 products similar to high-quality optical coatings and filters that are in top demand today:
1. Anti-Reflection (AR) Coatings
These are the most common type of optical coating. An AR coating consists of thin-film layers applied to a lens or window to reduce unwanted reflections and increase light transmission. They are in high demand for everything from eyeglasses and camera lenses to high-power laser systems, where reflections can be damaging.
2. Dichroic Filters (Dichroic Mirrors)
Also known as interference filters, these use thin-film coatings to reflect a specific range of wavelengths while transmitting others. This is a key difference from absorptive filters, which absorb the unwanted wavelengths. Dichroic filters are in top demand for applications like fluorescence microscopy, lighting, and stage lighting, where precise color separation is required.
3. Neutral Density (ND) Filters
A neutral density filter reduces the intensity of light without affecting its color. They are in high demand in photography and videography to control exposure in bright conditions, as well as in laser applications to attenuate beam power and prevent damage to sensitive components.
4. Bandpass Filters
These filters are designed to transmit a narrow “band” of wavelengths while blocking all others. They are crucial for a variety of applications, including:
- Fluorescence imaging: Isolating the emission signal from the excitation light.
- Machine vision: Enhancing contrast by selecting specific colors.
- Telecommunications: Wavelength division multiplexing (WDM) to carry multiple signals on a single optical fiber.
5. Hot Mirrors and Cold Mirrors
These are specialized dichroic filters that manage heat.
- Hot mirrors: Transmit visible light and reflect infrared (IR) light. They are in demand for projectors and cameras to protect internal components from heat.
- Cold mirrors: Reflect visible light and transmit IR light. They are used in lighting to separate heat from the illumination.
6. Polarizing Filters
These filters manage light based on its polarization. They are in high demand for applications like sunglasses (to reduce glare), photography (to enhance color and contrast), and in LCD displays.
7. Custom Coatings for Harsh Environments
This is a growing market for coatings designed to withstand extreme conditions. This includes Diamond-Like Carbon (DLC) coatings for scratch and abrasion resistance, as well as coatings that protect against salt spray, high humidity, and extreme temperatures. They are essential for military, aerospace, and outdoor applications.
8. Laser Line Filters
A laser line filter is a very narrow bandpass filter designed to transmit a specific laser wavelength while blocking all other ambient light. They are critical for applications like Raman spectroscopy, laser cleanup, and laser-based fluorescence, where high background light rejection is necessary.
9. Edge Filters
Edge filters are designed to either transmit or block all light above or below a certain wavelength. There are two types:
- Longpass filters: Transmit wavelengths longer than a specific cutoff.
- Shortpass filters: Transmit wavelengths shorter than a specific cutoff. They are widely used in spectroscopy and fluorescence imaging to separate different spectral regions.
10. Optical Windows with Coatings
While a standard optical window is just a protective plate, a high-quality optical window comes with specialized coatings. For example, a UV-fused silica window with a broadband anti-reflection coating is in high demand for deep UV applications, while a germanium window with a diamond-like carbon coating is used for IR cameras in harsh environments.

Optical filters
Optical Filters are devices, made of glass plane or plastic, that transmit or reject a certain wavelength or range of wavelengths. Optical filters can be divided into two categories: dichroic filters and absorptive filters. Dichroic filters, or interference filters, are color filters used to selectively and accurately pass light of a small range of colors …
