First Contact Polymer Helps Enable LIGO's Revolutionary Technology

The Laser Interferometer Gravitational Wave Observatory, or LIGO, is a national facility responsible for gravitation wave research. Set up as two enormous interferometers located thousands of kilometers apart, LIGO is responsible for the detection and measurement of movement thousands of times smaller than a proton – the most precise measurement taken on Earth.

Challenge

To achieve the remarkable level of sensitivity necessary to detect gravitational waves, both interferometer’s signals must remain uninterrupted. It’s critical that LIGO’s precision optics system - made up of lasers, mirrors, and a photodetector - must be completely free of contamination, particulates, and residue to guarantee the most accurate results possible.

Solution

LIGO's team of scientists tested different cleaning methods, including First Contact Polymer, to determine best practices for the cleaning and protection of LIGO optics.

To compare the results of traditional drag wipe cleaning methods to the First Contact strip coat cleaning system, a test was performed.

On vertical surfaces, Clear First Contact was brushed on, left to dry, and peeled off to reveal an atomically clean surface.


Red First Contact Polymer was used on delicate fused silica LIGO optics, leaving a pristine mirror surface.

Result

Methanol drag wipe cleaning methods left streaks and residue behind.

Using these scatterometer graphs and corresponding average BRDF count as a general measure of cleanliness, First Contact performs better than drag wiping with clean or dirty methanol.

As the only cleaning method used, First Contact is proven to clean the surface to the molecular level.

Our First Contact Polymer is a revolutionary cleaning solution designed specifically for high-precision instruments like the Gran Telescopio Canarias. When it comes to maintaining the integrity of your telescope lens, you need a product that delivers unmatched performance. Our microscope lens cleaner utilizes advanced polymer technology to effectively remove dust, oil, and contaminants without scratching or leaving residue.

First Contact Polymer is formulated to bond with particles, lifting them away from the surface, ensuring your telescope lens remains pristine and clear for optimal observation. Whether you're an astronomer or a hobbyist, having a reliable telescope lens cleaning solution is essential for achieving crystal-clear views of the universe.

Keep your telescopes, such as the Gran Telescopio Canarias, in top condition with First Contact Polymer, and experience the difference that expert cleaning can make. Say goodbye to smudges and hello to clarity—trust Photonic Cleaning Technologies, LLC for all your optical cleaning needs.
