Product Description

Gem Testing Gemology Darkfield With Camera Gemology Microscope

Product Description

Introduction:
SZG jewelry microscope, with Greenough optical system and special stand, fully meet the demands of various types of diamonds, crystals, gems and other jewelry.

Features:

1. Zoom optical system1:6.7

0.67x-4.5x zoom lens, magnification fulfills the needs of jewelry appearance observation and internal fine identification. Excellent optical system provides high defination, high contrast and high resolution images. And with a large depth of field, the final imaging has a strong 3D effect.
 

1. Multi-functional base and stand

Professional jewelry microscope stand, with the disk rotation, observation angle adjustment, body lifting and other functions, it can be adjusted according to the different habits and different samples.
 

1. Different illumination and imaging modalities

With fluorescent and halogen illumination, you can achieve parallel light, oblique light, transmitted light and other lighting methods, to achieve bright field, dark field and polarized light observation. Thus, you can analyze various components and characteristics of gem

The latest stereo microscope SZ6745N

Zoom lens, range of 0.67x-4.5x, working distance 100mm, high eyepoint diopter adjustable SZEWHT10X/22 to achieve 6.7x-45x magnification, to meet the needs of conventional jewelry testing.
 

Jewelry detection stand
The steady and decent stand, built-in 110-220V wide-voltage systems, ensure the illumination overcoming the restriction of voltage fluctuation and different voltage standards.
Flexible stand, retroverted 45°, hand-held design, make the angle adjustment and microscope moving more convenient and secure.
Focusing hand wheel can be adjusted. The focus range is 110mm. Then the different size jewelry can be detected.
 

Illumination
Transmission illumination system with 6V 30W halogen bulb, brightness adjustable, black disc-type lamp box has built-in dark field devices and bulb replacement devices, at same time ensuring better heat emission.
The upper illumination is 7W daylight fluorescent lamp, color, can reflect the true color of the surface of jewelry better. Hose connection, the lamp can be any angle as you need.
According to different needs, you can also choose 1W white LED, color, white a dimming function, hose connection. LED lamps are more stable brightness, long life, energy-saving and environment protection.

Auxiliary objectives
According to the size of the sample and the required magnification, you can choose a variety of auxiliary objectives to change the system's working distance and magnification.

Trinocular head and camera adapter
According to the size of target surface to select appropriate video adapter, new advanced SZ6745NTR trinocular zoom stereo microscope with a CCD can transfer the image observed in the microscopic to the monitor or computer for analysis, processing and preservation.

Gem clamp
Both sides of SZG platform, mounting holes for gem clamp are designed. You can select the position of gem clamp according to your own habits.
Gem clamp has two kinds of clamp, flat clamp and wire clamp. Flat clamp can hold some small small samples stably. Wire clamp for holding some larger samples in order to ensre enough light.

Product Parameters

Bright field-transmission observation of bottom light
Transmission observed under the bottom light, mainly used to observe the transparency, uniformity, internal inclusions, cracks and other features of the gem.

Bright field -reflective observation of upper light
Reflection observed under the upper light, mainly used to observe the gem's surface finish, stripes, feature, ribbons, cleavage planes etc.

Dark field observation
Under the transmitted light, rotating the dark field driving lever on the stage, dark field diaphragm can be put in the optical path, dark field can be observed.
Dark field observation is to use wide-angle oblique lighting the gem to find something with refraction characteristic inside, such as impurities, inclusions, stripes etc, to help determine the characteristics and level of the gem and to improve identification accuracy.
