3.What is 710nm IR Cut-Off Filter?

A 710nm IR cut-off filter is an optical bandpass filter that transmits visible light with wavelengths shorter than 710nm while blocking near-infrared light with wavelengths longer than 710nm.

4.What is typical application for 710nm IR Cut-Off Filter?

710nm IR Cut-Off Filters find extensive application across various fields:

Security & Surveillance: day/night IR-CUT switching for accurate color and enhanced NIR sensitivity.

Machine Vision: eliminates IR interference for color-faithful imaging.

Consumer Electronics: corrects color shift in smartphone and automotive cameras for human-eye-accurate output.

Spectral Analysis: front-end NIR stray light blocking for precision improvement.

Medical Imaging: enables accurate color in endoscopy and dermatology for reliable diagnosis.

What is key parameter when choose for suitable IR cut-off Filter?

When selecting IR cut-off filters, normally the following factors need to be taken into consideration：

Cut-off Wavelength: refers to the designated intermediated wavelength (e.g. 650nm) at transition from transmission to reflective zone, and measure at 50% transmittance.
Peak or Average Transmittance(in %): typically ≥90%, Higher transmittance might need Anti-reflective(AR) coating.
Blocking rate: usually in terms of optical density(OD), OD2-OD3 for standard and higher blocking rate will be OD4-OD6 per requirement.
Angle of Incidence (AOI): AOI need to be considered as Interference Filter is angle sensitive, 0° AOI by default, other AOI e.g. 30/45° need to be specified.
Physical and environmental requirement: Substrate type, dimensions and thickness, surface quality, and environmental durability.

Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical vacuum technology that apply depositing nano-materials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift. Besides, Liyuan optoelectronics have been focus on optical coating for more than 17 years ,and the company offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass Filters, Shortpass Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.

Remark: Because the interference type filter varies its performance at different angles, the spectral parameters usually determine its appearance color; moreover, the pictures in this link may originate from various shooting angles, so the actual color should therefore rely on the final spectral parameters required as the standard.
