1 General Information
This manual describes the use of the Thorlabs components for Raman Spectroscopy, a spec-
trograph, different front ends and adapters, suitable for varying applications.
Raman spectroscopy is a technique that detects and analyzes inelastic photon scattering,
known as Raman scattering. Because Raman scattering is material specific and provides a mo-
lecular fingerprint, Raman spectroscopy can be used to identify specific chemicals or mo-
lecules.
One challenge in Raman spectroscopy has long been the low signal-to-noise ratio (SNR) due to
the very weak Raman scattering signal. The Coded-Aperture (CODA) technology can overcome
the challenge of the low SNR as it uses a two dimensional matrix with a defined pattern of mul-
tiple slits instead of a single slit input aperture. This coded input aperture allows data acquisi-
tion from a larger sampling volume than a single slit input aperture. This in turn, enables higher
sampling rates and an increased SNR. Please find more general information on Raman spec-
troscopy and background on Coded-Aperture systems in the chapter Operating Principle .
RSB1(/M) Raman Spectrograph
The Thorlabs RSB1(/M) Raman Spectroscopy Base Unit features such a highly optimized spec-
trograph based on the CODA technology with a pseudo Hadamard mask of order 64 and an at-
tached CMOS camera (not removable). The geometric size of the Coded-Aperture's active area
is 3.159 mm x 2.304 mm. Due to the Coded-Aperture technology and the spatial averaging in
the analysis, the Thorlabs Raman spectrograph RSB1(/M) is superior in the analysis of complex
mixtures.
Beyond the Coded-Aperture technology, the RSB1(/M) Raman Spectroscopy Base Unit is de-
signed for 785 nm excitation and a detection range of 500 cm-1 to 1800 cm-1. The RSB1(/M)
Base Unit can be purchased in an imperial (RSB1) or metric version (RSB1/M). For the purpose
of this manual, RSB1(/M) refers to both versions.
To assemble a full Raman spectroscopy system, the RSB1(/M) needs to be equipped with a
front end which collects the scattered Raman signal for detection and analysis, an excitation
light source 785 nm, and a PC.
Note Excitation between 680 nm and 785 nm is possible with your system if your RSBR1(/M)
or RSBC1(/M) was built in 2023 or later. RSBR1(/M) and RSBC1(/M) built in 2021 or 2022 will
require a different bandpass filter for using a shorter wavelength excitation. For this, please
contact [e-mail]. Please be aware that the detection range in wavenumbers
(cm-1) changes when using a different excitation wavelength while the spectral range of the
spectrograph RSB1(/M) remains unchanged.
Thorlabs Front Ends RSBR1(/M) and RSBC1(/M)
Thorlabs offers different front ends for variable applications:
RSBR1(/M) reflective front end for analysis of powder and solid samples:
RSBR1(M) carries the optical modules which guide the laser light to a solid or powder sample,
collect back-scattered Raman signal from the sample and focus it onto the RSB1(/M) input
aperture. For laser light input, the RSBR1(/M) features an FC/PC connector. A sample table is
provided to place a specimen at the optimal focal plane. The RSBR1(/M) even allows to ana-
lyze samples that are transparently wrapped. The wrapping component can be eliminated from
the output spectrum provided that the focal volume is located within the sample.

Raman Spectroscopy Bundle Chapter 1: General Information
RSBC1(/M) cuvette front end for analysis of transparent, translucent, or semi-transparent
materials:
The RSBC1(/M) holds samples in 10 mm cuvettes and collects Raman scattered light in a 90°
geometry with respect to excitation. This is possible for transparent, translucent, or semi-trans-
parent materials. Compared to the reflective front end, due to the 90° geometry, this reduces
the amount of scattered laser light or Rayleigh scattering that enters the spectrograph. Systems
using the RSBC1(/M) can be modified to collect signal at a 180° geometry to accommodate for
polarization dependent Raman spectroscopy. For more information on polarization dependent
Raman Spectroscopy and the modification, please see the application note below.
Both front ends can be purchased as an imperial version (RSBR1, RSBC1) or a metric version
(RSBR1/M, RSBC1/M). For the purpose of this manual, RSBR1(/M) or RSBC1(/M) refers to
both versions, respectively.
RSBF2 fiber input adapter for analysis of fiber coupled Raman scattering
The RSBF2 fiber input adapter is designed for the RSB1(/M) to couple a fiber carrying Raman
scattering from a user setup to the RSB1(/M) base unit. The RSBF2 generates a rectangular fo-
cus of the Raman Signal which matches the rectangular input aperture of the RSB1(/M)
Thorlabs Raman bundle. The RSBF2 is optimized for Raman systems emitting singal from 650
nm to 1050 nm. The RSBF2 is universal for imperial or metric systems.
RSBA1 adapter for 60 mm cage systems attachment to RSB1(/M)
For custom-made solutions, Thorlabs offers the RSBA1 adapter to connect the RSB1(/M) to
Thorlabs 60 mm cage system components. Other custom-made front ends can be connected
to the RSB1(/M) using the SM1.5 thread at the input aperture.
For data acquisition and analysis, Thorlabs provides the OSA Software, Raman Edition
(Thorlabs OSA Raman Software) on the Modular Raman Spectroscopy Kit website. For soft-
ware updates, please see the chapter Software and Installation.
As an excitation light source, Thorlabs recommends the FPV785M laser with the CLD1015
laser driver. The modular design of the Thorlabs Raman bundle also allows use of alternative
lasers, fulfilling the laser requirements stated in this manual.
Attention
Please find all safety information and warnings concerning this product in the chapter Safety in
the Appendix.
Please note that safety of the assembled system is the responsibility of the assembler. This
refers in particular to laser safety for high-power lasers as used for Raman spectroscopy.

4 System Setup
The following chapter describes how to mount the base unit, the front ends, adapters and the
FPV785M laser. Guidance for custom-made system mounting is also provided.
4.1 Mounting RSB1(/M)
Mounting RSB1(/M) on the Breadboard
Please mount the RSB1(/M) Base Unit on the provided breadboard using the enclosed posts
and clamping forks. Position the RSB1(/M) such that there is enough space on the breadboard
to mount the front end, the light source, and any optional accessories such as polarizers or a
beam profiler.
Please use mounting holes 1 and 2 as shown here on the bottom of the RSB1(/M) for stability.
Height of Input Aperture
The height of the input aperture of the RSB1(/M) may differ between the metric and imperial
system due to the mounting posts.
When the included posts are used, the difference in height is as follows.
RSB1/M
RSB1
Height of Input Aperture above Optical Table
84.1 mm (3.31 in)
3.25 in (82.6 mm)
Note:
When a cage system is mounted to the RSB1(/M) Base Unit, mounting tap 1 next to the input
aperture can not be used as the RSBA1 mounting adapter needs this space. When planning to
mount the RBA1 adapter, please use the two more distal mounting taps 2 and 3.
Attention
Be aware that the mounting is less stable when using taps 2 and 3 are used. The RSB1(/M)
may fall over.
Attention
Please never touch the screws holding the grating (see 12 in Operating Elements RSB1(/M)).
The grating is calibrated for the camera and even small displacements will abolish the function-
ality of the Raman Spectroscope.
