System Accessories

This section contains standalone products and system-dependent products for CRS and CRS³ systems.

General Accessories


The S&I Quick change mount for Princeton Instruments SpectraPro and SpectraPro HRS monochromators provides the possibility to use the same detector port for up to three detectors, with each being aligned and in focus after the exchange.

The mounts will allow for up to six different array detectors being used on one dual-exit port spectrograph.

(First installation requires the presence of a technician, to set up the reference positions for each detector separately)

Detector adapters

In order to use third-party detectors on Princeton Instruments monochromators, you will often need a special adapter, to fix it to the detector mount.
We can provide adapters for the following manufacturers:

Princeton Instruments
Becker & Hickl
Raptor Photonics

Basic C-Mount adapter also available.
Please enquire for specific detector models or other manufacturers.

CRS³ Accessories

Custom microscope system

Aside from our standard integrated upright Olympus BX53, BX51WI and inverted IX73/iXplore microscopes, we also offer a custom build for extreme versatility and working space.
The custom built features a highly adaptable aluminium profile frame, equipped with upright condensers and objective z-drives by Olympus and Märzhäuser.

Like the full body Olympus microscopes, we can provide automation for white light, imaging camera, oculars and objective revolvers.
In terms of motorized XYZ mapping, we can still rely on Märzhäuser XYZ-Stepper- and Physik Instrumente XYZ-Piezostages, including support for Raman Autofocus and the AdFoCon system.

Line Focus

  • a cylindrical lens reshapes the laser spot into a line
  • the line is projected into a line focus on the sample through the objective
  • provides better energy distribution, without sacrificing too much power per area on the sample
  • in combination with fast-mapping on a motorized stage and or EMCCD detectors, the overall scanning speed of samples is significantly increased

Line Focus distribution on detector and on SiC wafer

External beam path extensions

Our beam path extensions aim at providing beam deliveries to customer specific external experiments and applications, either via free beam or fiber coupling.
The foremost feature is the ability to still fully utilize the systems functions, like Raman laser to sample delivery and signal delivery to the spectrograph for analysis, while keeping all internal equipment at your fingertips, like polarisation, signal filtering, and more.

External application specific coupling

If you desire to couple our system to specific applications, like SEM, AFM, transmission measurements or other, just enquire about possible solutions.

We also provide a series of standard coupling methods to systems by:
Nanonics, CryoVac, AttoCube… tbc

TriVista “reactivation”

Due to our more than 25-year long cooperation with Teledyne Princeton Instruments, S&I and Princeton Instruments TriVistas share a lot of base functions and options.
Therefore S&I is capable of providing upgrades, refurbishing and simple check-ups to both S&I and Princeton Instruments TriVista systems, that have been out of use for some time.
We can help you reactivate them for your projects.

We also provide reactivation of older 32-bit systems, to make them available for 64-bit conversion and use on modern computer systems and with modern equipment.

TriVista Accessories

Stokes-Antistokes Accessory

An adapter for Princeton Instruments 12mm slit assemblies.
When used on a Duo or TriVista system in subtractive mode, the slide in adapter will block the Rayleigh line, allowing for the user to see both Stokes- and Antistokes emissions simultaneously.

Comes as standard with any TriVista and TriVista CRS system.

Height Limiter Baffle

A three-position height adapter, to be used on the slide in adapter of 12mm slit assemblies. The slider will limit the slit height from normal 12mm, in several steps to a minimum of 2mm.
This will further increase the already excellent straylight reduction of the Princeton Instruments SpectraPro HRS monochromators and significantly improve stray light reduction in additive mode.

Optomechanical Bypass System

One of the most coveted features of the TriVista systems, this option will allow the user to bypass the first stage entrance of the TriVista, to enter the third (and optional even second stage) immediately. This way the TriVista can also be used in 3rd stage configuration only and be used like a MonoVista.
Due to the general loss of throughput on a three-stage system, exposure times can be significantly longer in TriVista mode than in MonoVista mode.

In order to get a quicker overview and peak information on their samples, the users might want to check it in 3rd stage mode first and then switch to TriVista mode, for longer exposure times.

Bypassing the first two stages bandpass of a TriVista however will require the use of Raman Edge-/Notchfilters, to block the Rayleigh line.
