Macroscope Portable Microscopes
Macroscope portable microscopes are designed to fill the need for superior image quality in simple, cost effective configurations for applications in research, production, quality control or whether superior image quality is essential, MACROSCOPE portable microscopes represent a significant departure from the current day trends towards more sophistication and more elaborate features.
The MACROSCOPE 45 is equivalent in performance to instruments costing thousands of dollars.
The Macroscope-25
Is a fixed magnification unit that provides 25 x magnifications over a field of view measuring approximately 8 mm (5⁄16"). It incorporates a double calibrated interchangeable measuring reticle providing precise measurements in both English and the metric system. By detaching the base and close-up lens MACROSCOPE 25 can be used for 8x distance viewing, and with formula included, make distance of height approximations.
The Macroscope-45A
Weighing less than 1 pound MACROSCOPE 45 is the ideal instrument for field or laboratory applications providing extraordinary optics. The MACROSCOPE 45 is much quicker and easier to use and it is camera adaptable. Most importantly, any MACROSCOPE 45 may be converted to a MACROSCOPE 25 for wider field viewing by means of the simple low cost conversion kit available; in addition, most MICROSCOPE 25 units may be upgraded to MACROSCOPE 45 by means of the appropriate kit.
Features:
- Extra wide field of view
- Positionally correct image
- Portable and easy to use
- Camera adaptable
- Excellent optical design
- Measuring reticle
- Superior image quality
- Diversify and numerous applications: Biology, archeology, botany, forensics, geology, entomology horticulture, numismatics and philately, quality control and textiles industries, electronics etc.

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
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
- Operating distance 1-12" without 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
