Lensed Led Gooseneck Lights Feaures:
Lens and diffuser in front of the led form a highly collimated beam of uniform light.
Flexible arm allows to position this source at a distance and angle to the object or specimen to achieve brightfield, oblique or
darkfield illumination. We offer lensed led gooseneck lights in visible spectrum, UV and IR, with one or two heads, and two types of bases - stand alone or
mountable on a standard 1.5" vertical boom. All gooseneck lights have embedded electronics - no need for external controller. Light intensity is
adjustable from 0 to maximum.
Lensed Led Gooseneck Lights Applications:
Brightfield, oblique or darkfield illumination for compound and stereo microscopes.
Transparent, semi-transparent or nearly colorless specimens are almost invisible when examined under transmitted brightfield illumination. Transmitted
oblique or darkfield illumination reveals transitions in refractive index or other optical path differences within the specimen which allows to observe the morfology and
internal structure of the specimen. Reflected oblique and darkfield illumination is usefull for examination of opaque specimens to emphasize edges and
surface texture.
