HCS402 Dual Heater Microscope Hot And Cold Stage
Instec’s HCS402 microscope hot and cold stage features a dual heater design which virtually eliminates vertical temperature gradients in the sample chamber. This makes the HCS402 temperature controlled environment an ideal choice for thicker samples or when the best available temperature uniformity is necessary. Top and bottom dual pane windows on the HCS402 stage are removable and exchangeable to meet a range of spectroscopic needs. The stage can be mounted vertically for applications requiring horizontal beam access to the sample chamber. The interior of the HCS402 is large enough to accommodate a variety of samples, including electro-optic devices and standard 25 mm x 75 mm microscope slides.
The integrated top cover heater provides supreme above-ambient temperature stability and uniformity. A must have for precision experiments!

*Working distances will be greater if optional spacers are used. 5, 8 or 10 mm aperture for transmitted light available by request.
Installation of frame skirt is required for stage operation below -60°C so that water condensation does not collect inside the sample chamber. When the skirt is in place, side loading of sample and XY positioning are not possible.
