With the rapid iteration of consumer electronics, automotive optoelectronics, and intelligent vision technology, camera modules and precision optical components are evolving toward higher resolution, miniaturization, ultra-high sensitivity and multi-scenario adaptive performance. From automotive ADAS vision systems, industrial machine vision cameras to smartphone and wearable device optical modules, end-market applications are placing increasingly stringent requirements on product environmental adaptability and long-term operational reliability.
Temperature reliability testing is an indispensable core link in optical product R&D, verification and mass production. Traditional integrated temperature test chambers face obvious technical bottlenecks in optical testing scenarios. The closed integral structure cannot support real-time external optical shooting, imaging analysis and parameter calibration under temperature cycling conditions. In addition, low-temperature testing environments easily generate surface fog and condensation, which interferes with imaging accuracy and leads to invalid test data. Meanwhile, standardized chamber structures cannot adapt to diversified fixture positioning and external test equipment docking of different camera module specifications, resulting in low test efficiency and poor compatibility.
Split-structure temperature test chambers with professional optical windows perfectly solves the pain points of isolated testing and environmental interference, and meets the industry’s demand for real-time, synchronous and high-precision optical performance verification under extreme temperature conditions.
Different from conventional integrated temperature chambers, it adopts an innovative split structural design, which perfectly separates and coordinates the internal temperature simulation environment and external optical detection system. The equipment can stably simulate high and low temperature, temperature cycling and other extreme environmental conditions, while supporting real-time external optical observation, imaging collection and performance testing, realizing one-stop synchronous completion of environmental simulation and optical parameter verification.
The chamber is equipped with professional high-grade optical glass window, which features ultra-high light transmittance, low optical distortion and excellent flatness. It effectively avoids light refraction, attenuation and imaging deviation caused by window materials, ensuring that the optical path is highly consistent and the collected imaging data is true and reliable during temperature testing. The optical window supports long-term high and low temperature alternating impact, with stable physical and optical properties, no deformation and no light attenuation, adapting to long-cycle reliability aging tests.
Aiming at the common industry problem of condensation and fogging on the window surface in low-temperature and high-humidity test environments, we configure a built-in integrated defogging system. The system can intelligently adjust the defogging state according to the internal temperature and humidity changes of the chamber, completely eliminate surface fog and water condensation, and maintain continuous clarity of the optical window in the full temperature range. It thoroughly solves the problem of blurred imaging and interrupted testing caused by low-temperature fogging, and guarantees 100% valid data collection for long-term optical testing.
The flexible split structure is the core differentiated advantage of the product. The internal cavity independently completes accurate temperature simulation and constant temperature maintenance, while the external space can be freely connected with optical detectors, industrial cameras, imaging analysis equipment and automatic test platforms. This design realizes physical isolation between the temperature simulation environment and the external test system, avoids equipment damage caused by temperature conduction, and supports real-time dynamic testing, continuous shooting and full-cycle data monitoring without opening the chamber door, greatly improving test efficiency and data continuity.
We provide personalized non-standard customized fixtures for different specifications of camera modules, lenses, optical sensors and precision optical components. The customized fixtures feature accurate positioning, firm fixation and strong compatibility, which can effectively avoid sample displacement and vibration deviation during temperature cycling tests. It supports multi-spec sample switching and batch fixed-point testing, and can be optimized and upgraded according to customer’s test standards and sample sizes, realizing targeted matching of different optical test scenarios.
