ThetaMetrisis - FR-Basic

_FR-Basic series

FR-Basic is a modular and expandable series of optical measurement instruments that share the same technological platform, the White Light Reflectance Spectroscopy. FR-Basic tools are tailored to customers' needs and are capable to be used in a wide range of diverse applications from standard Absorbance/Transmittance and Reflectance measurements, to Films Characterization under temperature and ambient controlled environment.

FR-Basic tools have been carefully designed to be assembled by modules. Each FR-Basic tool consists of five modules
Core Module,
Case Module,
Working Area Module,
Optical Fiber Configuration and
Cover Top Module.
The wide range of applications of standard configuration can be further expanded by the use of special accessories that are available. By choosing or combining different modules one can make the most suitable measurement and characterization set-up for any end-user needs. Figure 1, summarize the available options for each of the FR-Basic modules.

_Core Module options

Core module options refer to the required spectrometer type, spectral range and appropriate light source that are needed for the particular application. For more information please refer the Application page or contact us at info@thetametrisis.com.

Type	Spectral range	Thickness measurements range*
FR-Basic UV/VIS	200nm - 850nm	5nm - 20μm
FR-basic VIS/NIR	350nm - 1000nm	20nm - 100μm
FR-Basic UV/NIR-HR	200nm - 1100nm	5nm - 120μm
FR-Basic UV/NIR-SG	200nm - 950nm	5nm - 80μm
FR-Basic VIS/NIR-SG	350nm - 1100nm	20nm - 90μm
FR-Basic NIR	900nm - 1700nm	500nm - 200μm
FR-Basic D VIS/NIR	350nm - 1700nm	20nm - 200μm
FR-Basic D UV/NIR	200nm - 1700nm	5nm - 200μm

* Thickness measurement range depends on the spectral and refer to a single film layer with refractive index ~1.5 over a reflective substrate.

_Case Module options

Type A

In this case the optical connections are in the front panel for optimum spectrometer's sensitivity. When this option is selected, Cover Top can not be used.

Type B

In this case the optical connections are located on the back top of the case. This configuration supports all accessories and thus offers increased modularity of the unit.

_Working Area
Flat Aluminum 2mm thick anodized aluminum as cover panel
Teflon Cover 1cm thick teflon
Bench Top Optical breadboard with through-drilled 1cm thick anodized aluminium with M6 (or 1/4"-20) thread and standard hole pattern offset of 25mm (1"), for assembly optical components such as filters, holders etc.

Integrating Sphere Holder - Reflectance A Super Structure with X-Y-Z manual movement6, for precise positioning of the integrating sphere over the measurement area.
Integrating Sphere Holder - Reflectance A Super Structure with X-Y-Z manual movement6, for precise positioning of the integrating sphere over the measurement area.
Hot plate For real time measurements of reflectance and film thickness, under thermal treatment (up to 200^oC), e.g. polymer films (glass transition temperature, degradation temperature...), bioreactions* etc. It comes with a computer/manual operated PID temperature controller. It may be combined with an external chiller for cooling. Standrad size is 5" OD, other sizes are available on request. * requires a flow cell.
Liquid vessel For real time film measurements in liquid environment with or without stabilized temperature, e.g. for resist dissolution, coating resistance etc. It may combined with external chiller for cooling under environment temperature. The standard vessel can accommodate samples of any shape, up to 100mm in diameter. The solution volume is 450cc.
Gas Chamber For real time films measurements under controlled gas ambient, e.g. for swelling measurement of polymer film, coated resistance etc. It may be combined with hot plate and with external chiller for cooling.
