ATAGO has been the leader in refractometer technology for over 73 years. The history of Refractometers began with a basic model a simple analog instrument. Today, refractometers are highly sophisticated due to the advancement of technology and the incorporation of high precision electronics into a refractometer.
Digital refractometer and polarimeter manufacturers Bellingham + Stanley offer a wide range of refractometers and polarimeters via a network of trained distributors.
CRAIC Technologies manufactures superior microspectrophotometers for science and industrial applications. We specialize in the UV, visible and NIR regions and pride ourselves in making the finest tools for the finest minds.
Since CRAIC’s founding, our mission has been to become the leading provider of superior quality optical tools and superior support for the customers who use those tools. We manufacture the best quality microspectrophotometers and UV-visible-NIR microscopes and Raman microspectrometers bar none.
Since its inception, CRAIC has specialized in optical tools for the ultraviolet, visible, and near-infrared regions. Products include microspectrophotometers (also known as microspectrometers or microscope spectrometers) that is able to take spectra of samples smaller than a micron. CRAIC has also designed and built UV-visible-NIR range microscopes. Full spectral range fluorescence, transmission, and reflectance spectra and images can be acquired from any microscopic sample non-destructively and without contact with these tools. CRAIC manufactures both scientific grade systems in addition to specialized systems for industries such as semiconductor inspection and pharmaceutical metrology. CRAIC also makes NIST Traceable Standards, the only ones in the world specifically designed for microspectrophotometers, and specialized software packages.
CRAIC specializes in the following micro-analytical techniques: UV-Visible-NIR microspectroscopy, UV-visible-NIR microscopy, Color microspectroscopy, Transmission microspectroscopy & microscopy, Reflectance microspectroscopy & microscopy, Fluorescence microspectroscopy & microscopy, Polarization microspectroscopy & microscopy, Raman microspectroscopy, Film thickness measurements, Spectral modelling.
CRAIC has more experience designing, developing, manufacturing and installing microspectrophotometers than anyone. CRAIC is committed to maintaining the highest level excellence for ist’ products and service.

Filmetrics was founded in 1995 with the mission of making thin-film measurements simple and affordable. Prior to our arrival, film-thickness measurement instruments cost $50,000 or more and required advanced training. Single measurements took as long as an hour.
The Filmetrics approach, borne of the microelectronics and software revolution, results in film-thickness measurements that take less than a second – by operators who can be trained in minutes.
In just one click, we measure thin-film thickness by analyzing how the film reflects light. By measuring light not visible to the human eye, films as thin as 1nm and as thick as 13mm can be measured. And, because there are no moving parts, results are available in seconds: film thickness, color, refractive index, and even roughness.

JJ X-RAY is a Danish company that develops, designs and produces highly specialized components and assemblies for scientific x-ray, synchrotron radiation and neutron instrumentation.
We are widely known for our high precision and durable JJ X-Ray slits and collimators. Our standard component portfolio is constantly expanding. At present, it also includes:
Compound refractive lens (CRL) systems
Diamond Laue monochromators
Complete beamline solutions
Compact UHV slits
We look forward to, continuously, providing scientists and engineers around the world with high performance instrumentation and comprehensive counseling.
Slit systems are probably the most well-known product of JJ X-Ray. However, JJ X-Ray has a product portfolio which goes far beyond slits. Throughout the years, we have successfully provided many different types of components, sub-assemblies and even complete systems to our customers.
The components have typically been slit systems, high precision motion stages, diffractive optics systems, refractive optics systems, collimators, goniometers, end stations, SAXS systems as well as complete beamline solutions.
Below you will find a list of our present standard products.
A.KRÜSS Optronic has been famous for high-precision, state-of-the-art measuring instruments for over 200 years. It is the oldest company manufacturing optical instruments still in existence.

FilmTek metrology systems can measure a broad array of single and multi-layer films including metallic, semiconductor, amorphous, crystalline, and dielectric materials on virtually any substrate. FilmTek can simultaneously determine:
Multiple layer thicknesses (from <1Å to 250 microns)
Indices of refraction (both TE and TM components of index)
Extinction (absorption) coefficients
Energy band gap
Surface roughness and damage
Porosity, composition, and crystallinity (EMA model)

Sino Science & Technology Co., Ltd. located in Zhangzhou, which is a small, beautiful and calm city in CHINA mainland! We began our optical instruments business from 2001, having a factory with 3300 meter squares, 5 experts in optical and electronic designs. We have dozens of patents for refractometer, microscope and gemstone identify tools.
The refractometer and fiber inspection microscope were our first business at the beginning. In 2003, the gemstone identify instruments were introduced to our business. Now,we can make the full line instruments for gemstone test. With the quick growing in business, we invested to make all kinds lens and prisms. And we also distribute the scientific test instruments for lab using and all kinds of measuring work, such as caliper.

Since the start of our company in 1981, our business model has always been to sell the products we design, develop, and import from our overseas factories only through our worldwide network of dealers. We greatly respect the dynamics of the distribution network; this is why we’ve never changed. Our dealers always feel confident that any contact we may have with end-users (i.e. application discussions, technical assistance, drop shipments, etc.) will never result in us selling direct. This bond of trust we share with our dealers allows us to truly work together as a team. That being said, listed below are the other key elements you can always continue to expect from us:
With our many, many years of experience and expertise in the scientific products industry, we are able to provide you with the best value in laboratory equipment and accessories currently available. Our wide product lines cover a large percentage of the items which are used in most labs.
Whether your questions are related to technical specifications, scientific applications as they relate to our products, shipping methods, the status of an order, etc. — our top-rated customer service team will assist you to complete satisfaction.
In the internet age, speed is everything. We keep a very large inventory in our Kirkland, WA warehouse, so most orders ship the same day we receive them. If the item is in stock, it will always ship within 3 business days. Also, all orders are double-checked and professionally packed with care.
