Testing
Our commitment to precision and reliability is underscored by meticulous testing and analysis procedures. Leveraging an array of tools, including Interferometers, ETS Humidity, DSE Climatic, and Temperature, and Ascott Salt Fog test chambers, we conduct thorough evaluations across optical and environmental spectrums. These processes ensure the robustness of our products under diverse conditions.
In-house test equipment, such as Digital microscopes and Dynascopes, enhances our inspection capabilities, while our Class 6 Assembly Cleanroom provides a controlled environment for precision manufacturing. Additionally, our Laser Test Facility employs Laser Induced Damage Threshold (LIDT) testing, assuring the endurance and resilience of our laser optics against potential damage, contributing to the overall reliability of our optical solutions.
Our product testing employs a diverse range of tools, including Spectrophotometers and Interferometers for optical measurements, along with ETS Humidity, DSE Climatic and Temperature, and Ascott Salt Fog test chambers for environmental simulations.
Additionally, we utilize eraser and wiper abraders for wear testing and digital microscopes and dynascopes for detailed inspections. These varied methods ensure the comprehensive evaluation and consistent high-quality output of our products.
Spectrophotometers are essential in our product testing, ensuring quality and consistency. These devices measure light intensity in a spectrum part, enabling us to accurately determine our products' absorbance, transmittance, and reflectance. This is crucial for colour consistency across batches or when wavelength absorption indicates certain substances. The data we gather refines our manufacturing process, helping every product meet our high standards.
Interferometers play a key role in our optical testing, ensuring precision in our flat substrates. By causing light wave interference, we can measure Form Error, Transmitted Wavefront Error and Parallelism. Form Error reveals deviations from ideal surfaces, Transmitted Wavefront Error assesses optical performance, and Parallelism ensures substrate faces are exact parallels. This data refines our quality control, enhancing production and product standards.
Our ETS humidity test chambers are used to simulate diverse humidity levels, helping us understand how our products respond to different environmental stressors. We can thus assess the reliability and longevity of our products under high-humidity conditions. This insight informs our manufacturing process, ensuring that our products are designed to withstand a wide range of environmental conditions. The data from these tests is pivotal in our commitment to producing high-quality, durable coatings and filters.
We use DSE Climatic test chambers to verify the resilience of our products under varying climatic conditions. These chambers emulate a wide range of temperatures and humidity levels, enabling us to evaluate how our products withstand different environmental extremes. The data derived from these tests is integral to our mission of delivering top-tier, robust products.

Safeguarding the Future of Laser Optics with LIDT Testing
Our Laser Test Facility is a cornerstone of our operations and a testament to our dedication to precision, quality and resilience. With the application of Laser Induced Damage Threshold (LIDT) testing, we ascertain the robustness of our optics against laser-induced changes.
Our Laser Test Facility represents our ongoing commitment to ensuring the highest standards in laser optics. This is where we employ LIDT testing - an integral part of our process aimed at gauging the resilience of laser optics to intensive laser irradiation.
The LIDT test is a destructive testing method, purpose-built to measure the threshold of permanent laser-induced alterations in the surface or substrate of a sample. With the help of a high magnification differential interference contrast dark field microscope, we're able to detect even the most minute changes induced by laser exposure. This granular level of examination allows us to understand the endurance level of our optics, which is a key determinant of their overall performance and durability.
In the realm of laser optics, damage due to intense irradiation is a real concern. Damaged optical elements can potentially hamper the performance of laser systems, leading to issues down the line. By conducting rigorous LIDT tests at our facility, we strive to identify and rectify these potential problems ahead of time, significantly reducing the likelihood of unexpected or directed laser damage.
Our Laser Test Facility plays a significant role in the overall quality control process at G&H | Artemis. As we continue to leverage our sophisticated LIDT testing capabilities, we ensure that G&H | Artemis remains synonymous with exceptional quality, durability, and cutting-edge optical solutions.
