JDSU’s front surface mirrors provide the building blocks for laser beam printers

JDSU is a world-leading manufacturer of high quality front surface mirrors. We have achieved this position by supplying customers worldwide with quality mirrors, in high volume, on time, and at competitive prices for many years.

The Laser Beam Printer market demands printers with improved resolution and faster printing speeds. JDSU’s HR780A and HR780B Laser Beam Printer Mirrors are specifically designed to enhance laser beam printers.

HR780A offers the laser beam printer manufacturer the robust durability and
economy of aluminum-based glass mirrors, plus a typical reflectivity of >93% reflectance in the p-plane of polarization at 780 nm.

When economy is a key concern, the HR780B is an equally durable yet inexpensive alternative, with a typical reflectivity of >86% reflectance under the same conditions.

Environmental specifications

• Humidity Resistance
  The mirror coating shall show no deterioration after exposure to 24-hour humidity test of 49° C and 95% relative humidity.
• Abrasion Resistance
  The mirror coating shall show no damage after a 200-rub test with a cheesecloth pad approximately 3/8” (9.5 mm) diameter by 1/2” (12.7 mm) thick. The bearing force shall be one pound ±1/4 pound (454 g ±114 g).
• Coating Adhesion
  The mirror coating shall show no damage after 3M Scotch Brand No. 610 adhesive tape (or equivalent) is placed firmly against the coated surface and removed quickly.
• Corrosion Resistance
  The mirror coating shall show no deterioration after 24 hours of exposure to a salt fog test (5% NaCl by weight in water) at 35° C.
