Care information
Care information
High care information about CO2 laser lenses, fiber laser protective windows, and
fiber laser lenses is essential to ensure the optimal performance and longevity
of these critical components in laser systems. Here are some key points to consider:
CO2 Laser Lenses:
Cleaning:
Regularly clean CO2 laser lenses to remove dust, debris, and residue. Use a
soft, lint-free cloth or lens cleaning tissue. Avoid using abrasive materials
that may scratch the lens.
Handling:
Always handle CO2 lenses with clean hands or lint-free gloves to avoid transferring oils or contaminants onto the lens surface.
Storage:
Store lenses in a clean, dry, and dust-free environment to prevent damage and
maintain their integrity.
Alignment:
Properly align CO2 lenses within the laser system to ensure efficient laser
beam delivery and focus.
Inspection:
Regularly inspect lenses for signs of damage, scratches, or deterioration.
Replace any damaged or worn lenses promptly.
Fiber
Laser Protective Windows:
Cleaning:
Clean fiber laser protective windows with care to avoid scratches. Use a gentle
cleaning solution and a soft, lint-free cloth.
Protection:
Keep protective windows in place when the laser system is not in use to prevent
contamination and damage.
Replacement:
If protective windows become damaged, replace them immediately to maintain
laser system safety and performance.
Fiber Laser Lenses:
Cleaning:
Clean fiber laser lenses carefully to prevent damage. Use a lens cleaning
solution and a soft, lint-free cloth or lens tissue.
Handling:
Handle fiber laser lenses with care to avoid fingerprints, oils, or scratches
on the lens surface.
Alignment:
Properly align fiber laser lenses to ensure accurate laser beam focusing and
efficient performance.
Inspection:
Regularly inspect fiber laser lenses for signs of wear, damage, or contamination. Replace any compromised lenses promptly.
Environmental Considerations: Be mindful of environmental factors such as temperature and
humidity, as extreme conditions may affect lens performance.
Overall,
maintaining high care and attention to detail when handling, cleaning, and
storing CO2 laser lenses, fiber laser protective windows, and fiber laser
lenses will enhance their longevity and contribute to the smooth and reliable
operation of your laser systems. Always follow the manufacturer's guidelines
and best practices for each specific component to ensure optimal results.
Delivery and Shipping
Delivery and Shipping
FOR ITEMS IN STOCK:
Orders placed before 2:00 pm EST/EDT on a business day
(Monday - Friday) will ship the same day.
Orders placed after 2:00 pm EST/EDT may not be be shipped
until the next business day.
Our business hours are Monday to Friday, 9 am-4:30 pm.
Orders placed after business hours will not be processed
until the next business day.
Orders placed during the weekend (Saturday - Sunday) or
holiday will be shipped on the next business day.
All packages are shipped FOB ORIGIN – These shipping terms
are characteristic of a “SHIPMENT CONTRACT” and the seller bears the expense
and risk of putting the goods in the possession of the carrier. Title transfers to the buyer at the point when the goods leave the shipper’s loading dock but reverts back to the seller if the buyer follows the correct procedures of notifying the seller of “breach” by “rightfully revoking cceptance.” Even if “breach” has occurred, the buyer remains responsible for filing “carrier loss
claims.”
Product Description
The Silicon Phase Retardation Reflector (PRR) is a precision optical component designed for CO₂ laser beam delivery systems operating at wavelengths of 9.3–9.4µm.
Manufactured from single-crystal Silicon (Si), this reflector features a 50.8mm (2.00") diameter and nominal 5.0mm edge thickness.
Its specialized phase retardation coating produces a 90° ±3° phase shift between P- and S-polarized light at a 45° angle of incidence. When used with an appropriately oriented linearly polarized beam, this phase shift can produce circular polarization, helping support consistent laser processing in different cutting directions.
The reflector provides greater than 99.0% average reflectance at 9.3–9.4µm and is designed for precision infrared beam delivery applications.

Important Compatibility Information
This reflector is specifically designed for 9.3–9.4µm operation at a 45° angle of incidence.
The specified phase retardation performance should not be assumed to apply at 10.6µm or at other incidence angles.
Before ordering, verify the required operating wavelength, diameter, edge thickness, coating, polarization configuration, and mounting requirements.
The phase retardation coating is designed to modify the polarization state of the reflected beam. It is not a standard uncoated silicon mirror.
