​PR-1w Palmtop Raman Spectrometer
The PR-1w Palmtop Raman is an amazing new technology that includes a wide-range,
high-resolution spectrograph into a tiny form factor.
The PR-1w Palmtop Raman spectrometer is a compact unit that contains a powerful 50 mW 785 nm laser, coupled to a high resolution spectrograph with CMOS detector. Compared to many of the commercially available Raman instruments, the PR-1w is a user-friendly Raman spectrometer that can be used by virtually anyone with minimal training. It can be used in many different environments, and variety of measurement concepts, such as in-line and in-situ measurements. With a comprehensive range of optional accessories, the PR-1w can be optimized for specific applications.
Switch between FTIR and Raman
PR-1-ATR is a unit that attaches PR-1s/PR-1w to JASCO ATR (ATR PRO ONE X, ATR PRO 4X, ATR PRO ONE). By rotating the ATR unit, you can switch between FTIR and Raman, allowing for combined analysis without moving the sample.

​PR-1w Palmtop Raman Spectrometer Features
Simple Design & Operation
Connect to a PC, start the software and press the probe against the sample - acquisition starts immediately from the measurement button; there is no need for detailed settings, such as optical axis adjustment or focus adjustment. Most Raman systems typically can only measure down to around 400 cm. but the PR-1w Raman spectrometer can measure closer to the Rayleigh scatter down to 200 cm. This makes it possible to measure inorganic substances with peaks in the low wavenumber region.
Comprehensive Data Processing & Spectral Analysis
Suite cross-platform spectroscopy software includes a wide variety of analysis functions as standard, such as wavenumber calibration, fluorescence correction, and intensity correction. KnowItAll Informatics with spectra search of databases for the analysis and identification of up to 25,000 Raman spectra is also available as an option.
Adjustable Focal Distance
The focal position can be easily adjusted to change the measurement position from the surface to inside of the sample.
Compact Form-Factor with Sophisticated Optics
The PR-1w is a fixed range Palmtop Raman spectrometer with a 785 nm laser and a CMOS detector built into a compact housing.

Application
The PR-1w has wide spectral range 200 – 3,000 cm per pixel resolution that can be used for non-destructive analysis of solids, powders, and liquids, including the contents of transparent bags, vials, and cuvettes for qualitative and quantitative analysis.
​PR-1w Palmtop Raman Spectrometer Accessories
Vial Holder (PR-1-V)
The PR-1-V vial holder is used to measure liquid and powder samples in a light-shielding compartment and can be used with 2 mL vials.
Cuvette Holder (PR-1-C)
The PR-1-C cuvette holder is used to measure liquid samples in 10 mm x 10 mm cuvettes.
Z-Stage Mount with Sample Plates (PR-1-Z)
The convenient Z-height adjustable unit can be used for the measurement of a variety of samples: powders, liquids, and films.
PR-1-OL9/0L15/0L22
Optional longer working distance lenses can be used for measurements from 9 mm to 22 mm.
Protective Sample Chamber (PR-1-DS)
The PR-1-DS protective sample chamber has excellent light-shielding properties for highly reproducible measurements. Two different sample holders are available: liquid/powder and an ATR prism holder.
ATR Measurement Unit (PR-1-ATR)
The PR-1-ATR attaches the PR-1w Raman Spectrometer to an ATR PRO ONE X, PRO 4X, or PRO ONE. This mount switches between FTIR and Raman measurements, allowing combined analysis without moving the sample.

Parameters:
Laser Power
The Palmtop Raman spectrometer (PR-1w) contains a 785 nm laser that has three different power settings: Low/Medium/High (5 mW/15 mW/50 mW, respectively). The Raman signal (I) is directly proportional to the power of the laser (mW). As a result, the Raman signal will increase when a higher laser power is selected; however, increasing the laser power can potentially burn your sample. If you are concerned with damaging your sample, start with the laser at low power and slowly increase the laser power until you have a good Raman signal with no sample degradation.
Parameters:
Exposure and Accumulation
Raman spectrometers enable the control of data acquisition by adjusting the exposure time and the number of accumulations that are averaged together for a final spectrum. If a sample has weak Raman scattering, increasing the exposure time will result in a better Raman signal. Increasing the number of accumulations will increase the measurement time but also improve the S/N ratio.
The PR-1w Palmtop Raman Spectrometer uses an uncooled Complementary Metal Oxide Semiconductor (CMOS) sensor as its detector. Since the characteristics of a CMOS detector are very different from a Charge-Coupled Device (CCD) detector, which is standard in the NRS and RMP series of Raman spectrometers, the following should be taken into consideration:
-
A background measurement must be taken before each sample measurement.
-
In most practical uses, the maximum exposure time is 4 – 5 seconds.
-
The number of accumulations can be increased to improve the S/N ratio.
-
Detector saturation is more likely to occur
-
Pay attention to the installation environment.
