Coaxial lights

19 x 19 mm High-definition coaxial light (COS-ZT) (LS-COS18-R/G/B/W-ZT)

Model LS-COS18-R/G/B/W-ZT

Coaxial light with a light path and optical design different from conventional coaxial lights, eliminating the ghosting caused by refraction and transmission in the light path, so images stay sharp without distortion at small fields of view and high magnification. Can be made in different wavelengths.
