- Opton
These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products.

# Belongs to category:
Illuminators

# Description and specifications:
60-watt microscope illuminator for Carl Zeiss (Oberkochen, West Germany) Standard series microscopes.

The basic versions of Carl Zeiss Standard series microscopes are equipped with a base illuminator using a 6 V 15 W lamp. This can be replaced with:
a) a large 60-watt illuminator using a 12 V 60 W lamp
b) a halogen illuminator

This listing presents the illuminator described in option a), namely the 60 W incandescent lamp version.

Basic specifications of this illuminator:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Model: 60-watt illuminator
Lamp voltage: 12 V
Lamp house mounting method: circular dovetail
Cooling: passive. The entire large lamp house also serves as a heat sink, dissipating the heat generated by the 60-watt lamp
Lamp socket centering screws: yes, the lamp socket is equipped with centering screws
Diffuser: yes, inside the lamp house, in front of the lamp condenser lens (the so-called illumination collector), there is a matte diffuser mounted in a flip-out holder

This particular unit was removed from a Carl Zeiss Photomicroscope II. However, it is compatible with most microscopes of the Zeiss Standard series.

This illuminator fits the following microscopes:
- Zeiss Standard 16 / GFL
- Zeiss Standard WL / WL 89
- Zeiss Universal
- Zeiss Photomicroscope
- Zeiss Photomicroscope II
- Zeiss Photomicroscope III RS
- and also the Zeiss IM 35 / ICM 405 inverted microscope

The following is a quotation from the Zeiss Photomicroscope II instruction manual:

60-watt illuminator

Instead of the 6-v. 15-w base illuminator, the 60-watt illuminator may be firmly connected to the microscope stand. For this purpose, the collector tube with lamp condenser, 46 70 50, must be removed after unscrewing the bottom plate and replaced by the connecting tube, 46 70 41 (Fig. 15). The 60-watt illuminator is mounted in the usual manner with the aid of a dovetail ring, like a body tube, for example.

The variable transformer is identical to the one for the base illuminator and supplies voltages from 0 ... 20 volts. When this equipment is used, the red scale of the voltmeter applies.

Several important points should be mentioned:
- if your microscope is currently equipped with the standard 6 V 15 W illumination system, the illuminator mounting adapter must also be replaced (this is described in the instruction manual quoted above)
- the lamp house of this illuminator is finished in grey. Some Carl Zeiss Standard series microscopes have black, cream or hammered-finish housings. This illuminator is mechanically compatible with those models, although the colour may not be an aesthetically perfect match
- power supplies with a rated output of exactly 60 W are virtually unavailable on the second-hand market. In practice, 12 V 100 W power supplies are used to operate this light source
- please note that exactly the same (!) illuminator is also used on the Zeiss IM 35 / ICM 405 inverted microscopes. Please also refer to the description of illuminator No. 00697 in this database. YES – these are exactly the same illuminators. However, that particular unit was removed from an inverted microscope and therefore has its own separate description. You will also find additional photographs there. In the Zeiss IM 35 instruction manual, the lamp socket is referred to as "Lamp socket 60 P/N 46 80 15", while the lamp house is referred to as "Lamp housing with lamp condenser P/N 46 72 27"
- this illuminator can be used for both transmitted-light and reflected-light (EPI) illumination
- if you would like to manufacture your own DIY illuminator mounting adapter because you do not have the original Zeiss part (P/N 46 70 41), the following information may be useful: the circular dovetail on this illuminator has a diameter of 43 mm, which is the same as on many microscope condensers and mono-, binocular and trinocular microscope heads. This means that, for example, a microscope head mounting adapter can be used as the basis for manufacturing a custom DIY illuminator adapter

Important: The photographs show a lamp installed in the lamp socket. This lamp DOES NOT LIGHT because it is burned out. It is shown only so that you can see which lamp model is used in this illuminator.

# Examples of use
- if you own a Carl Zeiss Standard series microscope or Photomicroscope without an illuminator
- if you would like to replace your existing 6 V 15 W illuminator with a more powerful one
- if you already own this type of 60-watt illuminator but it has been damaged (for example, the lamp condenser lens has cracked)
