Chongguang Laboratory | Temperature Competition at the Millimeter Scale: An Analysis of Technical Challenges in Cold/Hot Stages

A high‑quality hot/cold stage features core components—silver or copper uniform‑temperature blocks—that are connected to the housing via only a limited number of contact points. At these interfaces, low‑thermal‑conductivity materials (such as thin‑walled stainless‑steel tubing and PEEK insulating shims) are employed to create “thermal bridges,” ensuring structural stability while significantly minimizing heat loss.

[New Product Launch] The Chongguang Ultra-Low-Temperature Optical Platform Has Been Successfully Developed

This model is a cryogenic optical platform with compressor‑based cooling, independently developed by Chongguang, offering an operating temperature range from 6 K to 330 K. Designed specifically for optical and electrical experiments in extreme low‑temperature environments, it is suitable for applications in low‑temperature Raman spectroscopy, quantum optics, the semiconductor industry, MEMS, superconductivity, electronics, physics, and materials science, among other research fields. The system employs compressor‑based refrigeration, eliminating the need for liquid helium and delivering vibration levels below 100 nm. It features an automated temperature‑control module that enables one‑click temperature switching. Compatible with microscopy, spectroscopic measurements, and scanning probe techniques, it can be integrated with optional components such as low‑temperature piezoelectric stages, fiber‑optic assemblies, and electrical connectors. The equipment has been deployed at the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences.

[New Product Launch] The Chongguang Ultra-Low-Temperature Displacement Probe Station Has Been Successfully Developed!

As quantum computing surges past a critical threshold, third‑generation semiconductor materials accelerate toward commercialization, and superconducting technologies enter the phase of engineering‑scale validation, cutting‑edge fields such as the semiconductor industry, MEMS microsystems, and condensed matter physics are confronting unprecedented challenges in precision measurement and control: How can we detect nanovolt‑level electrical signals in ultra‑cold environments approaching absolute zero while achieving distortion‑free transmission of 50 GHz high‑frequency signals? With material‑level characterization now entering an era of “extreme conditions,” a measurement instrument capable of transcending temperature limits and signal‑integrity barriers has become an essential enabler for both scientific research and industrial upgrading.

Chongguang Laboratory | Saying Goodbye to Temperature Overshoot: An In-Depth Analysis of How PID Control Achieves Research‑Grade Precision in Temperature Regulation

Overshoot and oscillation—these are the “number one enemies” of temperature control. A poor control algorithm is like a novice driver: it overreacts constantly, overheating the system and then cooling it down too much, causing the temperature to swing up and down like a roller coaster and failing to stabilize.
