Optonics will be introducing its super
polishing, ultra-low loss coating, precision optical machining, and optical
contact technologies at the International Photonics Industry Exhibition and
Conference 2020, which will be held Nov. 19-27 at KAPID online non-face-to-face
consultation room and the exhibition homepage.
The optical specialist Optonics possesses
super polishing, ultra low loss, high-LIDT coating, and precision optical
machining and optical contact tecnologies needed to manufacture highly difficult
laser optical parts. And based on these technologies, it is manufacturing the
core optical parts in optical-laser-RLG (ring laser gyroscope).
The company staff said, "Most of the
processes are performed in clean rooms and isothermal-isohumidity rooms to
ensure excellent quality and reproducibility, and by operating the
ISO9001/ISO14001 management system, we are producing products that are
competitive in the global market. We will do our best to secure sustainable
competitiveness by continuous technology development and recruiting talents,
and listen to our customers' opinions to provide the best products and
technologies."
Super polishing
Super polishing is a method of polishing in a state that is several tens of times smaller than abrasive particles used in ordinary processing. With super policing, the optical performance is improved by expressing the optical surface roughness on a sub-nano scale and scattering loss can be minimized. Also, by minimizing the potential internal defects like micro-crack that inevitably accompanies in a conventional polishing method, there is less stress and higher reliability, and surface defects (scratches/digs) and particles are also minimized, so that a perfect optical surface can be made. This superior optical surface performance guarantees ppm-class (0.000x%) loss characteristics in ultra-low-loss optical systems, and also guarantees high-performance laser optical components with high durability and long life without laser damage even in high-power laser optical systems.
Ultra-low loss coating technology
It is applied for the purpose of minimizing
loss in the process of coating a photofunctional dielectric thin film on an
optical substrate, and it includes the purity of the material constituting the
thin film using a super-polished substrate, and the density of the thin film,
and also optimizing physical/chemical/mechanical/environmental characteristics
and the thin film process. Especially, to express the ultra-low loss
characteristics, cleaning, etching, and heat treatment processes, which are the
pre and post process technologies including the thin film process itself, are
the keys. The finished ultra-low-loss coating product is measured with ppm
precision for scattering loss, absorption loss, and transmission loss, and also
observes the presence or absence of particles and scratches/digs with a high
magnification microscope. Ultra-low loss coating-based optical products are
applied as core component technologies in the field of laser parts in the
ultraviolet band, laser ultra-precise measurement, and inertial navigation
systems.
Precision optical machining & optical contact
It is a technology that realizes
parallelism and angular performance for optical materials (LTEM) with a very
low coefficient of thermal expansion on a scale of seconds, and also controls
machining tolerances for optical materials very precisely. The LTEM material,
which is precisely implemented geometrically, can be combined with parts to
express optically aligned conditions, or by combining several parts through
optical bonding between mounted parts to make an integrated module. It can be
applied to high-precision optical measurement modules or laser modules
with the stable temperature
characteristics of LTEM materials and high durability against the environment.
Optical bonding is a method of maintaining
the bonding very firmly by inducing van-der-waals on the bonding surface. Since
there is no adhesive, welding or mechanical method for bonding, it does not
cause deformation, displacement, or stress due to bonding. Also, the adhesion
power is very high, the optical interface disappears, and the adhesion is
maintained for a long time with excellent environmental characteristics.
Especially, when each unit part is manufactured with very precise dimensions,
the dimensional accuracy of the final product combined through optical bonding
can be maintained very precisely, so it is very useful for integrated and
combined use of precision processed optical parts.
Regarding the purpose of participating in
this online export conference, the company staff said, "We are experiencing
difficulties in face-to-face public relations due to COVID-19. As a solution
for this, we participated in a consultation. With this opportunity, we will
further accelerate the supply of core parts in the domestic and overseas
ultra-precision, ultra-low loss, and ultra-high output laser field."
