Q: What's ATR8500 Triple Band Raman Microscope Imaging & Mapping?

A: Optosky's newly launched ATR8500 designed fully auto & scan in one working set with optional triple wavelengths selection from 533nm, 633nm, 785nm, 830nm and 1064nm. 


Q: What's the advantage of ATR8500 Raman microscope?

A: Here are summarized software functions:

1st, Optosky's ATR8500 designed optimal optical path to improve the sensitivity up to 8 times higher than the miniature Raman microscope ATR8300. 

2nd, World-leading free space patent technology optimization.

3rd, ATR8500 designed user-friendly cabinet door to perform measurement at any time and space. It requires an exclusive room to perform the measurement in the dark condition in the past, but this new design can shut the door to perform accurate measurement without lighting. In addition, the inner light installed can be turned on after finishing measurement to see clearly inside. 

4th, ATR8500 allow for customized triple bands selection among 532nm, 633nm, 785nm, 830nm and 1064nm.

5th, ATR8500 designs auto-focus, auto-scan, and one button operate a scientific-grade conjugate or confocal Raman microscope.

6th, ATR8500 upgrade the laser spot size up to 1.6μm.


Q: Why many customers perfer to use ATR8500 Raman microscope?

A: Refer to our customers suggestions:
1. Chemical composition and structure of materials: Raman spectroscopy can distinguish different chemical structures and even include structural differences formed by different spatial arrangements of the same atoms.
2. Noncontact and nondestructive: Multiple analysis of the sample without causing damage. 
3. No sample preparation is required: If an optical microscope can be used to focus to the analysis area, its Raman spectrum can be acquired by means of a Raman spectrometer.
4. The size of the sample to be analyzed: Can be selected from a small amount of material (size < 1.6μmμ) to a sample spanning several centimeters. A good miniature Raman spectrometer can flexibly control the size of the sample to be collected.
5. Analysis through transparent containers and Windows: Most Raman analyses use light at visible or near-visible bands. As a result, a wealth of information can be collected easily, even when the sample is sealed in a transparent container (such as a vial or capillary), or in a sample bin with an observation window (such as a temperature or pressure bin).
6.You can analyze samples in aqueous solutions: such as suspensions or biological samples. There is no need for time-consuming extraction or drying, which may change the chemical composition of the sample. 
7. Raman spectroscopy can be used to analyze almost all materials molecular bonds: Almost all materials with molecular bonds can emit Raman scattering. The only exception is pure metal, which reflects only light.


Q: Which functions included in ATR8500 Raman microscope?

A: Here are introduction software summarizes:
