Release：2024-03-20 Clicks：1009

1. Product Introduction

The Ultra Low Temperature Optical Platform (GM-10K-SM) is a product designed for studying the optical properties of samples at low temperatures, which can characterize the characteristics of the optical properties of samples at low temperatures as a function of temperature.

The product adopts a combination of GM refrigeration and resistance heating to achieve precise control within the range of 10-330K. It can be integrated with other optical devices (such as microscopes, Raman spectrometers, etc.) for temperature variation in situ testing, and can also integrate a low-temperature pressure potential shifter for precise sample movement.

Ultra low temperature optical platforms can be widely used in fields such as semiconductor industry, MEMS, superconductivity, electronics, ferroelectronics, materials science, and materials science.
