The device uses a Joule Thomson micro cooler for temperature regulation, without the need for liquid refrigerant. The temperature range can reach 70K-730K. Temperature stability can reach; 0.1K。
Non liquid nitrogen variable temperature optical thermostat
Ultra compact liquid nitrogen free optical thermostatIt is a device used for conducting low and high temperature optical experiments. Using Joule-Thomson micro refrigeration platform, no liquid refrigerant required to provide70K—730KThe temperature range. Temperature stability can reach±0.1KThis platform has no mechanical vibration or electronic noise, making it an ideal choice for any vibration sensitive application. The optical thermostat adopts a sleeve shape, making sample loading very simple and fast. Optical experiments such as reflection, refraction, transmission, and Raman spectroscopy can be conducted at low temperatures.

This device uses Joule-Thomson micro coolerTemperature regulation without the need for liquid refrigerant, with a variable temperature range of up to70K-730KThe temperature stability can reach±0.1KThe platform can accept sample sizes of14mm´10mmAnd without mechanical vibration or electronic noise, it is an ideal choice for any vibration sensitive low-temperature application.

In optical experiments, there are usually several key factors, such as the material of the window and the distance between the window and the sample surface. To meet the needs of different experiments, we can provide different window materials and sizes, as well as suitable cavities and different working distances. The vacuum chamber adopts a sleeve shaped or opening and closing design, allowing users to easily access the sample and easily switch between samples. In addition, this design takes up very little space and is an ideal product for installation on a microscope platform.
