Introduction

Product Overview

The Ocean Optics Optical Transmittance Spectrophotometer (OTS) is a compact system consisting of a
USB2000+ Spectrometer, an HL2000-HP-FHSA light source and a FOIS integrating sphere that is
specifically designed for accurate, repeatable measurements of optical filters, glass and ophthalmic lenses.
OTS 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. The OTS is particularly useful for measuring tint color,
photopic transmittance and UV cutoff of ophthalmic lenses and for characterizing photochromic,
eletrochromic and sun lens materials.

1: Introduction

About the System

The OTS covers the 380-780 nm wavelength range and accepts samples from 10-150 mm in diameter and
up to 10 mm thickness. The system consists of the following components:

• High-resolution miniature linear CCD-

array USB2000 Spectrometer configured
for 380-780 nm (SLIT-50, Grating #1)

• High-power, tungsten halogen light

source

• Fiber optic integrating sphere for

collecting signal transmitted through the
sample

• Optics for improved beam collimation

and spectral sensitivity distribution
(including a BG34 Schott standard
colored glass filter for greater sensitivity
and less noise in the total visible
spectrum)

• Short optical fiber to channel signal from the integrating sphere to the spectrometer

• Customized lens transmittance and color calculation software measures and displays up to 10

measurements at once. This custom software calculates T(avg 380-780nm), Luminous
Transmittance Tv, and color: L* a* b*, hue (h) and Chroma (C*).
