Micro Optical Chamber

 

A miniature optical chamber (MOC) for optical measurements versus temperature

– Low weight (300 g), small volume (50cc), low profile (24.5mm) Aluminum chamber

– Distance from top of sample stage to top of viewport : < 3mm

– 5 versions covering various temperature ranges

     1) -40 ℃ ~ +200 ℃ (Peltier type, MOC-PT)

     2) -40 ℃ ~ +170 ℃ (Peltier type, MOC-PTH)

          : optical measurements in transmission mode also possible

     3) RT ~ +450 ℃ (Ceramic Heater type, MOC-CHL)

     4) RT ~ +750 ℃ (Ceramic Heater type, MOC-CHH)

     5) 77K ~ 300K (Liquid Nitrogen type, MOC-LN2)

– Up to Ø =40 mm Sapphire or Fused Silica window

Micro Probe Station (77K~300K)

 

LN₂ (77 ~ 300 K)

Liquid Nitrogen type Micro Probe Station (MPS-LN₂) is a subminiature probe station with vacuum and temperature control functions. It can measure the electrical and dielectric properties of thin films in the temperature range of 77K to 300K. Also, it is possible to use a microscope and a sapphire viewport cover for optical measurements. There are other options including an optical fiber cover and an installation of high voltage terminals.

Features

– Easy Probing at 77K ~ 300 K

– 20K/min Maximum Cooling Rate

– Compact Internal Volume ( < 100 cc)

– Vacuum Tight

Applications

– Raman

– EL & PL

– Photovoltaic

– I-V Measurement

– FET Characterization Test

– Reflectivity

– Thermal conductivity(3 ω method)

– Thermal hysteresis

– Hall Measurement

 

Optical Cryostat - Microscopy (4.2K~350K)

The DE204*F-DMX-20-OM is our Ultra Low Vibration Closed Cycle Cryostat for Optical Micrscopy applications such as MicroRaman and Micro Photoluminescence. The DE204*F-DMX-20-OM uses a Helium Exchange Gas to decouple the sample from the cold tip of the DE204 Cryocooler. This prevents almost all vibration from being transmitted to the sample.  Sample vibrations of 3-5 nm have been demonstrated by users. Due to the exchange gas being less conductive, the base temperature will increase by 4-5K and the cooling capacity is roughly cut in half at varying temperatures. 

Features

 Ultra Low Vibrations (3-5 nm)

 Supports working distances as small as 1.5mm

 Continuously Adjustable Sample Holder (1.5-7 mm)

 Low Profile Windows

 Cold Tip Down Orientation

 Fully customizable

Applications

 Micro Raman

 Micro Photoluminescence (Micro-PL)

 Micro Spectroscopy

 Micro FTIR

 Low Vibration Optical Experiments

 Magneto-Optical Kerr Effect (MOKE)
