Reticles * Measuring Reticle
Reticle A is designed for general laboratory use (5 mm long, with 0.1mm divisions) and reticle B (4⁄16" long, 1⁄64" divisions) is most frequently used in textiles or electronics, and where measurement in mils is required. Reticle C (5000 µm long, with 50 µm divisions) is calibrated in microns and helpful for pesticide droplet size measurements or anywhere measurements in microns are required.

R-90 Ring
Light
Precision Adjustable Ring Light
R-90P Ring Light
The patented Chiu R-90 ring light is the first precision adjustable, 8- point ring light for stereomicroscopes. It provides uniform, interference-free illumination over a wide distance range and enables users to precisely adjust light output to specific applications. The R- 90’s "glide" system enables fast effortless adjustment to change contrast, eliminating glare without altering the stereomicroscopes optics. The light output is brilliant and shadows are virtually eliminated. The ring’s 8-point light sources are the polished ends of optical glass fibers mounted on tilting carriers.
Tilting is accomplished via a sophisticated mechanical rotating disk, which uniformly directs the motion of the 8 light openings to a single convergence point. The operating distance is 0 –12". The adjustable R-90 ring light also features dark-field advantage allowing it to be used in a broad variety of scientific, industrial and commercial applications.
Features
- Full 360° shadow-free, uniform. And cool illuminating for stereomicroscopes.
- Patented Chiu "glide" adjustment system
- Black anodized
- Rugged aluminum construction
- Dark field capability
- Operating distance: 0-24" with collimating lenses

R-90M Ring Light - MUNCHKIN
The Chiu R-90M "Munchkin is
the smallest 8-point adjustable
ring light in existence. The"Munchkin’s" simultaneous
pinpointing of light is achieved as
the 8 light sources are precision
mounted in unique "gliding"
carriers, providing the uniformity
of a single convergence point. R-
90M’s signifi-cantly smaller size,
simul-taneous light pinpointing
and non-reflected black anodized
coating enable users to adjust
light output to match their
specific applications. Light output
is brilliant, cool and perfectly
balanced.
The "Munchkin’s" patented glide system is activated via a slidemounted, milled edge thumb wheel. This simultaneously adjusts all (8) point light sources from 0 to 90°. R-90M is effective over the full 360° range with a temperature operating range of–40°F to +600°F. The precision system’s 8-point light sources are the highly polished terminations of the system’s optical glass fibers.The R-90M also offers dark-field capability.
Features:
- Full 360° shadow-free, uniform. And cool illuminating.
- Patented Chiu "glide" adjustment system
- Significantly smaller size
- Rugged aluminum construction
- Dark-field capability
- Non-reflected black anodized finish
- Synchronized light pinpointing
- User-variable convergence point
- Finest quality optical glass
- Ultra compact
