Optrans Corporation, in partnership with Marktech Optoelectronics, today announced the release of new ultraviolet and near-ultraviolet LEDs at 365 nm, 395 nm, and 405 nm. These additions expand the companies' already broad portfolio of UV LEDs, offering OEMs and design engineers enhanced options for curing, fluorescence, forensics, disinfection, NDT inspection, and specialty applications across multiple industries. The new UV LED products offer high optical power output in a cost-effective, molded-through-hole package.

New 365 nm UVA LED
- Optrans USFZ366C5 (Marktech MTE3660C1-UV) No Shoulder
- Optrans USFZ366C1 (Marktech MTE3660C5-UV) Shoulder for positioning 3 mm and 5 mm water-clear 365 nm UVA LEDs delivering high brightness and exceptional reliability for demanding applications. Typical uses include:
-
- Deep curing of adhesives, inks, and coatings
- Fluorescence excitation in non-destructive testing (NDT-FP), mineralogy, and document validation
- Forensics applications, such as detecting trace bodily fluids and other evidence
- Specialized uses in reptile and aquatic research
New 395 nm UVA LEDs
- Optrans USF395N1 (Marktech MTE3950N1-UV) - Round lens
- Optrans USF395N2 (Marktech MTE3950N2-UV) - Flat lens
These versatile 395 nm emitters are ideal for general-purpose curing, 3D printing, hobbyist projects, counterfeit detection, and household inspection (blood or body fluid contamination, pet stains). The visible purple glow allows users to track curing progress with ease.
New 405 nm Near-UV LEDs
- Optrans VSF405N1 (Marktech MTE4050N1-UV) - Round lens
- Optrans VSF405N2 (Marktech MTE4050N2-UV) - Flat lens
405 nm sits at the edge of the visible spectrum, enabling deep penetration into adhesives, resins, and biofilms. These LEDs are particularly effective for:
- Cationic polymerization and oxygen-inhibition resistant curing
- Thick coating, adhesive, potting compound, and 3D resin curing
- High-gloss, tack-free finishes in inks and coatings
- Continuous disinfection of occupied spaces, with reduced impact on skin and eyes compared to deep UV wavelengths
Overview of Applications by Wavelength
- 365 nm: Deep curing, fluorescence inspection, document validation, forensics, mineralogy, reptile health, and non-destructive testing.
- 395 nm: Versatile curing, 3D printing, counterfeit detection, hobbyist/crafting, and household inspection.
- 405 nm: Deep and thick curing, cationic polymerization, advanced surface curing, and visible-light-based disinfection.
