Accessories
Various accessories, up to 13 kg, can be adapted onto the dovetail microscope interface. Weight discs can be added or removed
to the D-balance unit and allow to align the balancing range to the customer’s equipment. The recommendation in the assembly
manual (2 heavy discs and 2 light discs mounted) covers the weight range of 7.3 kg up to 11,3 kg, which will fit to the most
common configurations. If the customer’s equipment is out of this range, discs need to be added or removed:
Serial number: OH4-20056 to 20196
Number of weight discs Load Optics carrier [kg]
Heavy Light Min. Max.
2 1 7.5 11.0
2 2 8.3 12.0
2 3 9.0 13.0
Serial number: From OH4-20206

Heavy Light Min. Max.
2 1 6.5 10.5
2* 2 7.3 11.3
2 3 8.0 12.0
* Standard configuration
Generally, accessories from the M525 serial do fit to the OH4 system. CAN handles and footswitches can be assigned individually
for each user (see User manual Doc.Code 10 714367, configuration menu, page 48). A mouth switch can be connected as well.
The current options as
• Leica DI C500 / IGS
• Leica ULT500
• Fluorescence: FL400 , FL800, FL400/800
• all MDRS4 Touchscreens in combination with the MDRS4
are possible to be integrated to the Leica OH4 system.
