  • Typical wavelength tuning: ~0.02nm/deg. C;

CAUTION, UV LIGHT: These devices emit high intensity ultraviolet (UV) light, which is harmful to skin, eyes, and may cause cancer. Avoid exposure to UV light, use protective glasses and cover your skin.

Do not look directly into the operating deep-ultraviolet LED as it may cause damage to the eyes. If looking into the operating LED is necessary, be sure to wear ultraviolet light protective glasses.

IEC62471 “Photobiological Safety of Lamps and Lamp Systems” defines exposure limits of electromagnetic radiation in the wavelength range from 200 nm to 3000 nm for each possible hazard (to the skin, eye, and retina). The deep ultraviolet light emitted from this product can be classified as belonging to the following hazards. It is recommended to understand the content of the standard before using the product.

This product is intended to be used for a general purpose (industry or consumer equipment) .
