Description
Description
Brand: LD-Teemm
Color: FL: 2.5"/63.5mm
Features:
- 1. Material: GaAs, Diam: 20mm/ 0.79", Focal length: 63.5mm/2.5", Thickness: approximate 2.2mm / 0.087", Usage: CO2 Laser Lens for higher power CO2 laser engraving, cutting machine
- 2. Compatible power: Dia.15mm/18mm/19.05mm/20mm, 40W-200W; Dia.25mm/25.4mm, 40W-400W; Dia.27.94mm/28mm, Up to 600W CO2 laser resistance;
- 3. High Transmittance: To obtain superior transmittance, GaAs crystals are grown by Chemical Vapor Deposition process. Please note: GaAs Focus lens appear in different colors under different light.
- 4. GaAs material is a chemically inert, non-hygroscopic and highly pure product that has high resistance to thermal shock and stability in virtually all environments, can work under higher temperature and with longer work life.
- 5. Double-sided Solid Coating, demonstrates superior CO2 laser transmittance and is employed as the transmission optical components used in CO2 laser processing.
Binding: Office Product
model number: LD-D20-F63.5-GaAs
Part Number: LD-D20-F63.5-GaAs
Details: How to Determine Focal Length?
The Focal Length is the Distance Between the Focal Lens and the cutter/engraver Material.
When install the Lens, Make Sure the Focal Lens: Convex Face to Laser, Concave Face to Material.
Notice:
1. Make sure the optical path is corrected;
2. Remember to turn on the air pump when working;
3. Make sure the lens is clean and free from condensation.
How to Clean Laser Lens and Mirrors?
Step 1 Cleaning for Light Contamination (dust, lint particles) Use an air bulb to blow off any loose contaminants from the optic surface before proceeding to the cleaning steps.
Step 2 Cleaning for Light Contamination (smudges, fingerprints) Lay the lens tissue on the optic's surface. Using an eyedropper, squeeze a few drops of acetone onto the lens tissue, wetting the complete optic's diameter. Without lifting the lens tissue, drag the lens tissue across the optic just fast enough so that the liquid evaporates behind the tissue. This should leave no streaks.
Step 3 Cleaning for Moderate Contamination (spittle, oils) Dampen an unused cotton swab or cotton ball with white distilled vinegar. Using light pressure, wipe the optic's surface with the damp cotton. Wipe excess distilled vinegar with a clean dry cotton swab. Immediately dampen a cotton swab or cotton ball with acetone. Gently wipe the optic's surface to remove any acetic acid.
Package Dimensions: 2.8 x 2.8 x 0.8 inches
