OD6 notch filter

OD6 notch filter

All products are sold individually as standard specification items. We provide short delivery times due to complete stock availability.

The TECHSPEC OD6 notch filter features high blocking performance and a wide transmission band, making it ideal for use in laser analysis applications where specific wavelengths must be blocked to maximize system performance. The TECHSPEC OD6 notch filter can be used, for example, in Raman spectrometers to eliminate unwanted noise from the excitation laser light source, achieving the best signal-to-noise ratio. This optical filter employs hard coating, ensuring that its performance is not degraded by time, temperature, or humidity. Each optical filter is secured in a black anodized aluminum frame with laser engraving, making it easy to handle, identify the product, and determine the installation orientation. For the product lineup, specifications, and sales prices of standard products, please visit the relevant product page on the official website of Edmund Optics Japan Co., Ltd. (accessible from the product homepage linked above). *You can download the catalog featuring this product from the link below, which is provided by Edmund Optics Japan.

StopLine Notch Filter

StopLine Notch Filter

Extremely high laser light blocking value (>OD6)

Semrock's notch filters are highly effective in the field of Raman spectroscopy when there is a need to detect anti-Stokes light, and in the field of fluorescence imaging when performing laser excitation (including Multi-Photon Applications). Additionally, Semrock's filters feature an ion-sputtered hard coat. Like other filters, they offer very high transmittance, durability, and excellent cost performance. 【Features】 ○ Very high laser light blocking value (>OD6) For more details, please contact us or download the catalog.

High Performance OD 6 Narrow Notch Filter

High Performance OD 6 Narrow Notch Filter

Narrow bandwidth, high blocking performance, high transmittance

This notch filter is a hard-coated filter with high blocking performance and a narrow bandwidth. It blocks only the narrow wavelength range before and after a specific wavelength, while allowing other wavelength ranges to pass through, enabling spectral separation. In Raman spectroscopy, both Stokes Raman scattering light (longer wavelength than the laser) and anti-Stokes Raman scattering light (shorter wavelength than the laser) can be detected simultaneously.

Notch filter

Notch filter

High precision, integration, stability

A notch filter is also known as a band-stop or band-reject filter. It can transmit most wavelengths while significantly attenuating light within a specific wavelength range (the stop band).

Notch filter (band-stop filter, rugate filter)

Notch filter (band-stop filter, rugate filter)

Craftsman's Point: Achieved optical properties with a periodically varying refractive index. Application: Expected applications in notable fields such as Raman spectroscopy.

We will achieve optical characteristics that have not been realized before by periodically changing the refractive index. Conventional optical filters (optical thin films) consist of alternating layers of high-refractive-index and low-refractive-index films, which exhibit specific optical properties. In contrast, notch filters (band-stop filters) are deposition products designed to periodically change the refractive index in the thickness direction. A characteristic feature is that no optically unnecessary ripple occurs outside the stopband. We can achieve optical characteristics that were not possible with previous optical thin film processing. (Do you have such challenges?) ■ Is it possible to reflect only around the wavelength of 532nm? ■ I would like the unnecessary parts to be unable to transmit optically. ■ Notch filter? Band-stop filter? Rugate filter? ■ I have heard that the measurement difficulty after deposition is high; can you accommodate this?

Short delivery time with stock sales! All items available for purchase from one piece.

Edmund Optics offers a wide range of optical filters, including a series of notch filters. Edmund Optics' notch filters feature blocking capabilities of OD 4 or OD 6 and can accommodate multi-notch configurations. The transmission stopband of the OD 4 notch filter is in a narrow range of just ±2.5% from the center wavelength, achieving a reflectivity of over 99% at the specified laser wavelength. OD 6 notch filters are used in applications that require high blocking only for narrow wavelength ranges while needing broad transparency for other wavelengths. Applications for OD 6 notch filters include laser-based Raman spectroscopy, fluorescence microscopy, and integration into life science systems. Multi-notch filters are used in applications that require the blocking of multiple narrowband transmissions with a single filter.
