High-durability glass-like bonding technology

A glass-like bonding film is used to bond substrates together.

Thin and always beautiful!— A must-see for those with problems such as service life and aberrations in bonded parts — *Approximately 100X better photostability than our conventional adhesive bond *Extremely high heat resistance *Ultra-thin bonding surface

Sample applications

  • Optical pick-up engines
  • Projectors
  • Displays
  • Automotive products
  • Solar panels
  • Microscopes
  • Flexible displays

Benefits of high-durability glass-like bonding technology (when applied on a wavelength plate)

Deterioration over time when irradiated with a laser
Test Conditions 1 Energy density: 1 W/mm2, Temperature: 85 °C environment, Irradiation time: 1,000 hr Glass-like bond Adhesive bond

The wavelength plate with the glass-like bond showed no signs of deterioration even after being irradiated by a laser with an energy density of 1 W/mm2, so the energy density of the laser was increased to the max. value of 27.4 W/mm2 to finally precipitate deterioration. The transmittance of the sample using the adhesive bond deteriorated 1% after 40 minutes, while the glass-like bond lasted 60 hours before exhibiting the same level of deterioration. The glass-like bond thus proved to have approximately 100 times greater photostability and heat resistance.

Effects of bonding layers on wavefronts

The thickness of the GL bonding layer is about 1/50th (approx. 100 nm or 0.1 µm) that of the conventional adhesive layer, thus mitigating transmitted wavefront aberrations.

The keys to high-durability glass-like bonding technology

Here, we give you a peek behind the processes used in our original glass-like bonding technology.
