Cerna Mini Microscopes Chapter 3: Description

Chapter 3 Description

The Cerna Mini Microscopes provide simple microscope configurations that are
ideal for experiments requiring simple imaging. Thorlabs offers four microscope
configurations: SFM2 (Cerna Mini Microscope), SFM (Cerna Mini Microscope with
Epi-Illuminator Module), SFMGFP (Cerna Mini Microscope with Epi-Illuminator
Module for GFP/Alexa Fluor® 488 with CCD Camera), and SFMGFP2 (Cerna Mini
Microscope with Epi-Illuminator Module for GFP/Alexa Fluor® 488 with sCMOS
Camera).

The SFM2 consists of a motorized microscope body and camera port. Similarly,
SFM, consists of the same base components with the addition of an illumination
cube housing module (WFA2002). Both allow you to add your own camera, filter
cube, and light source to suit your experimental needs. The motorized objective
holder provides 1" of vertical focusing adjustment for the 10X objective. The
motorized Microscope Body has ample space beneath the objective for adding
sample stages. The C-Mount threaded Camera Port is compatible with most
industry-standard cameras.

The SFMGFP and SFMGFP2 microscopes each consist of a motorized
microscope body, a camera port, a filter cube, a light source, an LED collimation
module, an objective, a scientific camera, and an LED driver.

The epi-illuminator module accepts a variety of Thorlabs’ mounted LEDs.
Currently, we offer two types of LED collimation modules (SFM22 and SFM80) to
connect the LEDs to the epi-illuminator module. The SFMGFP and SFMGFP2
each ship with an SFM80 module. For two LED collimation modules, replace the
SFM Epi adapter at the rear of the WFA2002 module with a DFM1 fluorescence
filter cube, a C4W-CC cage cube connector, and an SM1CP2 end cap.

4.3 Cerna Mini Microscope Setup

Note: To set up the SFM and SFM2 microscopes, follow the procedure in Section

4.3.1. For full functionality, the SFM will require the user to purchase an objective,
light source, filter cube, fluorescence filter set, collimator and digital camera. The
SFM2 will require an objective, light source, and digital camera.

Requirements: The following additional accessories (not included) are required
for installation of the microscope:

 1.5 mm Hex Key
 2 mm Hex Key
 2.5 mm Hex Key
 5/64" Hex Key

4.3.1 Microscope

1. Use four SHCS (Socket Head Cap Screw) (M6 for metric, 1/4"-20 x 1/2"
for imperial) and washers to mount the Microscope Body onto the optical
table/breadboard.

2. Use a 5/64" hex key to remove the three shipping plates on the
Microscope Body.

3. Skip this step for SFM2. For SFM, use a 2 mm hex key to mount the Filter
Cube Housing onto the Dovetail Plate.

4.3.2 Fluorescence Filter Installation

The SFMGFP and SFMGFP2 each ship with an MDF-GFP filter.
Note: The SFM module does not come with a filter cube nor a filter set. Use filter

cube item # MDFM-MF2 to install your filter set in the Filter Cube Housing.
To install the MDF-GFP filter:

Figure 8 Replacing the Filter Set

1. Use a 1.5 mm hex key to remove the screws (2X) from either side of the
Filter Cube Housing cover.

2. Use a 2.5 mm hex key to loosen the screw at the center of the cover to
slide out the filter cube.

3. Install your filter set inside the filter cube. See the MDFM-MF2 manual for
detailed instructions- https://www.thorlabs.com/manuals.cfm

4. Slide the filter cube on the Filter Cube Housing cover and tighten the
screw at the center of the cover.

Cerna Mini Microscopes Chapter 4: Getting Started

4.3.3 LED Power Source Installation

For easy installation, the Filter Cube Housing included in the SFMGFP and
SFMGFP2 configurations comes with a pre-installed LED and SFM80 collimation
tube.

1. Use two SHCS to mount the T-Cube LED Driver onto the optical
table/breadboard.

2. Connect the LED to the T-Cube LED Driver.

3. Connect the power supply from the T-Cube LED Driver to a standard
power outlet.

Cerna Mini Microscopes Chapter 9: Regulatory

Wheelie Bin Logo

Chapter 9 Regulatory

As required by the WEEE (Waste Electrical and Electronic Equipment Directive)
of the European Community and the corresponding national laws, Thorlabs offers

all end users in the EC the possibility to return “end of life” units without incurring

disposal charges.

 This offer is valid for Thorlabs electrical and electronic equipment:
 Sold after August 13, 2005
 Marked correspondingly with the crossed out

“wheelie bin” logo (see right)

 Sold to a company or institute within the EC
 Currently owned by a company or institute

within the EC

 Still complete, not disassembled and not

contaminated

As the WEEE directive applies to self-contained
operational electrical and electronic products, this end of
life take back service does not refer to other Thorlabs products, such as:

 Pure OEM products, that means assemblies to be built into a unit by the

user (e.g. OEM laser driver cards)

 Components
 Mechanics and optics
 Left over parts of units disassembled by the user (PCB’s, housings etc.).

If you wish to return a Thorlabs unit for waste recovery, please contact Thorlabs or
your nearest dealer for further information.

Waste Treatment is Your Own Responsibility

If you do not return an “end of life” unit to Thorlabs, you must hand it to a company

specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public
waste disposal site.

Ecological Background

It is well known that WEEE pollutes the environment by releasing toxic products
during decomposition. The aim of the European RoHS directive is to reduce the
content of toxic substances in electronic products in the future.

The intent of the WEEE directive is to enforce the recycling of WEEE. A controlled
recycling of end of life products will thereby avoid negative impacts on the
environment.
