DESCRIPTION
Instec's HCS621GXY gas-tight stage is a versatile tool designed for applications where a wide temperature range and control over the atmosphere are critical. This stage features a Ø28mm silver heating and cooling block and 2mm transmission aperture, providing the user with exceptional temperature uniformity. The gas-tight chamber provides a sealed enviroment for gas purge to avoid condensation or oxidation, or for controlled humidity studies. A low working distance of 5mm makes the HCS621GXY compatible with a wide range of optical systems, often without the need to add long working distance objectives. Integrated sample XY can be used to move the sample across ther thermal block without repositioning the thermal stage.
Choose from a variety of base-model add ons such as IR windows, active sample cooling systems, sample clips, or mounting adaptors.
Upgrade to the HCS621GXY+ model to customize the stage with special options such as increased transmission aperture size, customized covers, electrical feedthroughs and much more!

OPTIONS
HCS621GXY Base-Model Options
Add-on options for the HCS621GXY base model are listed below. These items can be added at any time, and can even be installed by the end-user in the field. When adding a cooling system to an existing HCS621GXY system, it may be necessary to upload a new parameter file to the temperature controller.
Active Sample Cooling The standard HCS621GXY supports precision temperature control from room temperature to 600°C. Enable active sample cooling with one of our LN2
suction-pump cooling systems to unlock active cooling rates as high as -50°C/min and a lower temperature limit of -190°C.
Note: When cooling below -60, it is highly recommended to utilize gas-tight stage body to prevent condensation and ice formation via a gas-purge or low-vacuum.

Window Size and Viewing Angle
The standard HCS621GXy has a vgas-tight chamber lid with a viewing aperture of 18mm (22mm glass window) with a viewing angle of ±57.0° from
normal. For applications which require a larger observation area and/or a larger viewing angle, alternate chamber lids are available. Larger window sizes
increase the viewing area and angle, but comes at the cost of slightly reduced temperature uniformity. Customization of the bottom viewing aperture
is possible, but requires upgrading to the HCS621GXY+ model. If large observation windows are required on both the top and bottom surfaces, take a look at
Instec's -IRM stage models.
- 18mm aperture lid (Standard)
PN: R0220-HCS621GXY
- 27mm aperture lid
PN: R03170-HCS621GXY
Window Material
The HCS621GXY utilizes removable and exchangeable windows to optimize performance for any wavelength. Base-model options are
shown below, but specialized options are available per request with the HCS621GXY+ model.
Note: The exact window part number depends on desired chamber lid, as multiple sizes are available

Sample Mounting
The HCS621GXY is typically used in a horizontal configuration with the integrated XY positioners and uses gravity to secure the sample against the thermal block. In cases where more thermal contact is required, samples are not perfectly flat, or a special mounting solution is desirable, alternate sample
mounting options are available for the HCS621GXY. Threaded holes on the sample area are included with each HCS621GXY base model, and a
set of up to 3 spring loaded sample clips can be added to conveniently secure tricky samples, or to secure sample when the stage is used in a vertical
configuration.
Note: Spring-loaded sample clips are NOT compatible with the Integrated XY positioners when used with certain samples (ie. very thin microscope slide covers).
Consult sales@instec.com for more information on whether your sample may be used in a vertical configuration.

Environmental Control
With its Gas-tight chamber, the HCS621GXY base model is capable of positive pressure gas-purge up to 0.5 Bar or very rough evacuation down to 1mBar. Gas ports are avialable in either straight or right angle orientations.
Right angle ports are generally more low-profile, and may be prefferable for certain applications. Relative humidity control is also avialable via our RHC01 relative
humidity controller.

Mounting Adapters
Mounting adaptors allow the HCS621GXY to be easily mounted onto your optical instrument of choice. All HCS621GXY models include side-mounted
L-brackets and tapped holes on the base for easy mounting to any instrument. Optional mounting adaptors are available for Instec's TPM-CX40,
Olympus, Leica, and many more microscope models. For the full list of mounting adaptors, contact sales@instec.com.
Note: Vertical mounting configurations may require sample fixture clips (SFC) to ensure compatibility.
- None (Standard)
- Vertical
- Horizontal
- Vertical with rotation
Special options for HCS621GXY+ customizable model
Upgrade to HCS621GXY+ for access to special options including:
Transmission Aperture
Some applications require larger transmission apertures than others- whether it be to see more of a sample, allow for more light transmission, or for
compatibility with specialized instruments. However, larger transmission apertures also result in larger thermal gradients across the observation area,
decreasing the temperature uniformity. Tune the HCS621GXY+ transmission aperture size to optimize the temperature uniformity while maximizing the
transmission aperture size.
- 2mm aperture (Standard)
- 4mm aperture
PN: AP4-HCS621GXY
Electrical Feedthroughs
For applications that require optical access with simultaneous temperature control and electrical testing, a range of gas-tight electrical feedthroughs may be
added to the HCS621GXY+ customizable model. The HCS621GXY+ supports up to 2 additional standalone electrical feedthroughs, which may
consist of a combination of up to 2 of any electrical feedthrough types. BNC type feedthroughs are available in two configurations: Grounded, where the
outer BNC conductor is connected to earth ground for shielding, and Floating, where the outer BNC conductor is left floating relative to earth ground
allowing the shielding conductor to be used as a second signal conductor. The Floating BNC configuration includes a second pogo-pin terminal for
each feedthrough.
- 1x or 2x vacuum blanks (Standard)
PN: F0V-HCS621GXY
- 1x or 2x Grounded BNC Connectors with pogo pin
terminals
PN: F1V-HCS621GXY
- 1x or 2x Floating BNC Connectors with
2x pogo pin terminals each
PN: F2V-HCS621GX
- Customized standalone electrical feedthrough (DB-9,
ribbon-cable, fiber optic, RF and much more!)
Upgraded Temperature Controller Options
The HCS621GXY is designed for use with Instec's mK2000 series temperature controllers. While the switching PID controller is recommended for most
applications, in cases where low electrical noise is critical, the temperature controller may be upgraded to an LVDC output model. Furthermore, the
mK2000 itself can be customized with various add-on options such as additional monitoring sensors, analog voltage output and more....
- mK2000B with switching PID output (Standard)
PN: mK2000B
- mK2000B with LVDC output upgrade
PN: mK2000B-LVDC
- Additional monitoring sensor for mK2000B
