Asahi Spectra Co. (ASC) was founded in 1970 in Tokyo, Japan by 3 engineers. ASC has been developing a vacuum deposition technology such as ion assisted deposition (IAD) and ion beam sputtering (IBS) , which achieve hard coating, excellent durability for environment (humidity, low or high temperature, thermal shock or vacuum) and stability of spectral performance. By now our optical filters have contributed in various markets such as astronomy, semiconductor, biotechnology, education and so on.
Nowadays, customer requirements are becoming more complicated as optical innovation advances, and most requirements cannot be satisfied by just optical filter technology. So we have been trying to expand our field to optical instruments based on our 40 years accumulated optical know-how as you can see how professional our optical instruments are.
Our integrated manufacturing process by both filter and instrument specialists is the most competitive advantage against “other only-optical-filter makers”.

AXIC, Inc. was founded in 1980 as a company to develop surface science equipment for the semiconductor, electronics, and general scientific community. Initial developments focused on x-ray and electron beam analysis of surfaces for compositional and film thickness analysis. These developments lead to the introduction of a stand alone x-ray fluorescence unit which was easily operated by fab personnel for the measurement of film composition and thickness. AXIC, Inc. now produces 3 XRF systems for coatings analysis in both development and production applications for the semiconductor, magnetic, and superconductor industries.
In 1992, AXIC entered the market of producing laser based reflectometers for the measurement of film thickness, index of refraction, and film absorption properties of transparent/translucent films for the semiconductor, optical and magnetics industries.
Shortly after, AXIC commenced the manufacture of plasma tools for cleaning, photoresist stripping, reactive ion etch (RIE), and plasma enhanced chemical vapor deposition (PECVD). Today these offerings include the MultiMode HF8, PlasmaStar, and BenchMark 800-II. Units are ideally suited for research and development and small scale productions. The plasma tools can be configured in various ways to meet the end users’ specific requirements.
BaySpec, Inc., founded in 1999 with 100% manufacturing in the USA (San Jose, California), is a vertically integrated spectral sensing company. The company designs, manufactures and markets advanced spectral instruments, including UV-VIS-NIR-SWIR spectrometers, benchtop and portable NIR/SWIR and Raman analyzers, confocal Raman microscopes, hyperspectral imagers, mass spectrometers, and OEM spectral engines and components. R&D Applications include:
Materials: Material characterization is an ideal application area for Raman spectroscopy, due to its high chemical specificity and rapid, non-contact measurement. Solid, liquid, or gaseous, nearly all materials possess a unique Raman spectral fingerprint. The technique can be readily scaled to microscopic approaches, allowing interrogation of extremely small volumes and samples, such as nanomaterials. Characterization of nanomaterials is critical to determining structural and conformational properties. Raman spectroscopy is a highly efficient technique to study the electronic properties, compositions, and mechanical stresses in these materials, all of which can manifest in Raman band shape and frequency shift.
Semiconductor: Raman spectroscopy has proven to be one of the most effective tools for characterization of semiconductor properties and for manufacturing process/quality control because materials such as Si, SiGe, InGaAs, GaAs, GaN, and graphene exhibit precise, distinct Raman bands. Applied in a microscopic approach, the Raman technique has been successfully implemented to determine microstructure composition on thin-films, strain in the multilayer device, and to identify defects across the wafer surface.
Process/Reaction: Unlike conventional UV-Vis and NIR monitoring techniques, Raman spectroscopy provides molecular specificity in real-time measurements of gas, liquid, and solid samples, both natural and synthetic. These attributes are responsible for the emerging reliance on Raman spectroscopy for a number of online process and reaction monitoring applications. Numerous sampling options, including fiber optic probes with long reach and stand-off probes for measuring inside containers and vessels make the technique adaptable to a myriad of environments and conditions.
Surface-Enhanced Raman: Surface-enhanced Raman spectroscopy (SERS) utilizes specialized metal substrates to allow Raman signal enhancement up to 10 orders of magnitude. This phenomenon occurs when the molecules of interest are in very close proximity to the metal substrate, and is generally used for evaporated solutions or particle-surface characterization. The enhanced Raman signal with SERS has extended its applications in many fields, such as biological studies, to quantify trace substances or identify very small structures such as cell surface proteins. Intracellular SERS is also possible, via the injection of metallic nanoparticles, to study internal structures and analytes.
COOKE VACUUM designs and manufactures a wide range of standard and custom high and ultrahigh vacuum systems intended for research and production. With five decades of experience, and thousands of units in the field, COOKE VACUUM has come to symbolize economy and versatility,
Cooke Vacuum Products was established in the late 1950’s during an exciting period of experimentation in vacuum technology, especially thin film coating and materials research. From the beginning, Cooke had to pioneer new applications and new tools for the emerging semiconductor and optical industries, and for the related research laboratories.
Over the next decades, Cooke continued to support R&D by developing pumping systems, resistance evaporation, electron-beam, sputtering, and plasma sources, often in close collaboration with customers. Vacuum environmental chambers were developed for the space industry, encapsulation and bake systems for early flat panel displays. New, and highly specialized equipment was made for the quartz crystal industry, as well as for production of printing foil, then holographic foil. We were there to make the first OLED systems, and the first glove-box processors.
Because of the emphasis on custom solutions, the company has remained relatively small, and is well-known for its ability to “engineer on demand” more than for volume production.
Thin Film Deposition: Thermal Resistance; Electron Beam; Sputter; PLD; OLED and Glove Box Systems.
Etch/Ash/Surface Treatment: Plasma Etch; Reactive Ion Etch; Surface Activation and Modification.
Test and Specials: Environmental Test; Space Simulators; Vacuum Ovens: Laser Die Attach.
