Ocean Optics - Inventor of the World's First Miniature Spectrometer
|
 This simple, yet elegant system
is ideal for accurate,
repeatable measurements of
optical filters, glass and
ophthalmic lenses.
We’ve combined our expertise in
miniature spectrometers and accessories
with experience as a manufacturer of
precision optics to create a compact
system for real-time transmittance
measurement of ophthalmic lenses and
other optical components.
The Ocean Optics Optical
Transmittance Spectrophotometer
(OTiS) is ideal for both in-line
and in-lab applications where
transmittance accuracy (to +/-
1.0%) and precision (+/- 0.1%)
are critical. Common
applications include measurement
of optical coatings, windows and
filters, and glass and plastic
components.
About the System
The OTiS covers the 380-780 nm
wavelength range and accepts samples
from 10-150 mm in diameter and up to 10 mm
thickness. The system comprises several
components:
-
High-resolution
miniature linear CCD-array
spectrometer configured for 380-780
nm
-
High-power, 20-watt
tungsten halogen light source
-
Fiber optic
integrating sphere for collecting
signal transmitted through the
sample
-
Optics for improved
beam collimation and spectral
sensitivity distribution
-
Sample fixture
(z-stage) to hold sample in place
and exclude ambient light
-
Short optical fiber
to channel signal from the
integrating sphere to the
spectrometer
-
Customized lens
transmittance and color calculation
