GEMOLOGY

OPTIKA GEMOLOGY Series includes stereomicroscopes purposely designed for stone inspection and stone setting. Jewels and gems have a variety of grade, which ultimately influence their value and cost on the market; therefore it is important to have solutions that are purposely designed for gemology.

Choose between 20mm or 22mm field of view and simple or gemological stand, depending by the model.

Especially OPTIGEM Series offers the ideal configuration, with multiple options for illumination and contrast techniques, such as incident, transmitted and oblique brightfield / darkfield, polarization and immersion analysis. They come with a special optical condenser configuration to ensure real, perfect darkfield application. OPTIGEM-1 & OPTIGEM-2 are two-in-one gemology instruments that can be used both in vertical and horizontal position in a very easy way, just by turning one knob: the horizontal position extends the use of a gemological microscope, giving the possibility to perform immersion analysis by submerging a sample in liquid.

Specifically Designed for Specialists

Gemological stereomicroscopes are meant to help with stone inspection and stone setting.
Jewels and gems have a variety of grades (or quality levels), which ultimately influence their value
and cost on the market; therefore it is important to have solutions that are purposely designed
for gemology. These stereomicroscopes are equipped with iris and darkfield condenser on the
bottom light source, and with a set of on stage tweezers to hold the stone in place.

Much More Than Gemological Stereomicroscopes

OPTIGEM-1 & OPTIGEM-2 are two-in-one gemology instruments that can be used both in vertical and horizontal position in a very easy way, just by turning one knob (no disassembling and re-assembling operations are required). The horizontal position extends the use of a gemological microscope, giving the possibility to perform immersion analysis by submerging a sample in liquid. If the stone’s refractive index is close to the liquid’s one, immersion makes the interior more visible by reducing the effects of refraction and surface reflection. This enables you to see a gem’s inclusions or color distribution more easily. Immersion is also necessary to see crystal growth structures, which might help you separate natural from synthetic corundum. Features like curved growth striae in flame-fusion synthetics, or separation planes in assembled stones, are often far easier to see when the stone is immersed.

Incredibly Versatile Operations

OPTIGEM Series offers multiple options for illumination and contrast techniques, such as
incident, transmitted and oblique brightfield darkfield, polarization and immersion analysis (only on Optigem 1 & 2).
They come with a special (see the dedicated chapter for further information) optical condenser
configuration to ensure real, perfect darkfield application.

Ultrabright LED Condenser for Optimized Illumination

An ultrabright LED-based electronic condenser with intensity control allows to switch from brightfield to darkfield;
it also produces perfectly the colourvof daylight. The condenser uses a new optical configuration especially created in order to obtain a perfect darkfield application.

Dedicated LED Illumination For Outstanding Results During Grading

The requirement for a pure white (6.3000 K), particularly high intensity light is because only
incident light is seen: a flexible arm can be freely positioned and the brightness of the LED
illumination accurately adjusted. LED transmitted illumination is available through a diffusing disc
(for brightfield) or as a side-emitting LED ring (darkflield, with black background) only on Optigem 1 & 2.
A selector gives the chance to set the microscope in 3 configurations: brightfield only, darkfield
only, or both brightfield and darkfield.

ST-202 – Polarizing analisys kit

Polarization technique allows to quickly determine if the stone at hand is isotropic or anisotropic or, at best, to determine the optic character of gemstones (twin planes, strain, pleochroism, etc.).  It is also the preferred tool for separating synthetic Quartz from its natural counterparts. In addition, the polarizing microscope may be very useful for distinguishing solid inclusions from negative inclusions as well as for spotting polysynthetic twinning.
