On the track of precision optics and spectroscopic technology, “micron-level” precision control often begins with the protection of “cleanroom-grade” production environments.
In 2020, the dual-base ultra-cleanroom laboratories invested and built by ***the “Specialized, Sophisticated, Distinctive, and Innovative Little Giant” enterprise CHNSpec were officially put into operation. Today, this “clean fortress” rooted in the two major production workshops in Hangzhou and Taizhou has reached the important milestone of five years of successful operation. Over the past five years, with high-standard hardware configurations and comprehensive authoritative system certifications, it has built a solid barrier for the manufacturing of core products and has become a vivid testament to CHNSpec’s deep commitment to precision manufacturing and its unwavering dedication to quality.
As a technology enterprise focused on the research, development, and production of precision optical inspection equipment, CHNSpec is well aware that for precision optical components, a single speck of dust or a slight temperature difference can become a “fatal hidden risk” affecting product performance. For this reason, the dual-base ultra-cleanroom laboratories were constructed with a total floor area exceeding 500 square meters. With a layout featuring “division of labor, collaboration, and full-domain controllability,” they achieve dual guarantees of production capacity and quality: the Hangzhou workshop focuses on the manufacturing of core components, controlling component precision from the source; the Taizhou workshop undertakes finished product assembly and testing, ensuring that final product quality meets standards.
The laboratories strictly adhere to the Class 100,000 cleanroom standard, with no more than 100,000 airborne particles of 0.5 microns or larger per cubic meter, fundamentally avoiding contamination risks and safeguarding the precision and stability of every device delivered from the factory.
To achieve precise environmental control, robust equipment is the key support. CHNSpec’s ultra-cleanrooms are fully equipped with TICA purification units, which integrate high-efficiency filtration, precise temperature control, and constant humidity regulation. These systems can stabilize workshop temperatures within 20–24°C and control relative humidity within the ** range of 45%–65%, providing constant and suitable environmental conditions for the processing, assembly, and calibration of precision components.
At the same time, the laboratories have established a comprehensive environmental monitoring system, regularly inspecting key indicators such as particulate content, temperature, and humidity to ensure that the clean environment continuously meets standards. This ensures that “ultra-clean standards” are not merely a written commitment, but a rigid guideline running through the entire production process.
Beyond hardware, system certification is another layer of assurance for the high-standard operation of the ultra-cleanrooms. At present, CHNSpec’s production centers have passed three major authoritative system certifications: ISO9001:2015 Quality Management System Certification, ISO14001:2015 Environmental Management System Certification, and ISO45001:2018 Occupational Health and Safety Management System Certification.
This signifies that the operation of the ultra-cleanrooms not only meets the stringent cleanliness requirements of product manufacturing, but also achieves comprehensive standardized management in quality control, environmental compliance, and employee health and safety, vividly interpreting the company’s development philosophy of “quality first, responsibility foremost.”
