SP102 Thin Plastic Scintillator Sheets for Beta Detection
SP102 Plastic Scintillator is a thin polystyrene-based material designed for beta-ray measurement and charged-particle detection. ATR Crystal supplies custom thin plastic scintillator sheets for review against your detector dimensions and application requirements.
When selecting plastic scintillator for beta detection, consider the target beta-energy range, active area, sheet thickness, entrance window and mechanical support. Final detection performance depends on the complete detector arrangement, including optical coupling, photosensor and electronics.
For a quotation, send the dimensions, thickness, quantity and any available drawing. Include surface-finish, wrapping and sensor-interface requirements where specified. If some details are undecided, send the information you already have so the remaining requirements can be identified.

Advantages of SP102 Thin Plastic Scintillator
- Optimized for beta detectionThin SP102 sheets support beta measurement while reducing unnecessary gamma interaction compared with thick plastic scintillator blocks.
- Fast scintillation responseThe 2.4 ns decay time supports fast counting and timing-sensitive beta detector designs.
- Blue emissionThe 423 nm emission peak matches many PMTs, SiPMs and photodiodes used in radiation instruments.
- Non-hygroscopic materialPolystyrene-based plastic scintillator is not hygroscopic, simplifying handling and detector integration compared with hygroscopic crystal scintillators.
- Custom thin-panel formatsThickness, active area, edge finish, surface quality and mounting features can be reviewed for custom detector housings.
- Useful mechanical stabilitySP102 can be machined and integrated into detector assemblies when temperature, stress and mounting conditions are controlled.
Detector Integration Considerations
SP102 should be specified together with the detector window, optical sensor, electronics and mechanical housing. For low-energy beta particles, the entrance window, air gap, protective film and scintillator thickness strongly influence detection efficiency. If the instrument must reject gamma background, the scintillator thickness, shielding, threshold and calibration method should be reviewed together.
For PM2.5 beta attenuation instruments, provide the beta source, detector geometry, filter tape position, measurement distance and required active area. For surface contamination meters, provide the target beta source, expected energy range, active area, window design and uniformity requirement.
How to Specify SP102 Thin Plastic Scintillators
For an accurate SP102 quotation, define the target beta source or energy range, total panel size, active area, thickness, thickness tolerance, surface finish, optical coupling method, reflector, sensor type, window material, housing design and required inspection method.
If the detector needs a very low beta threshold, include the entrance window material, air gap, source-to-detector distance and calibration geometry. If the product will be used in a beta attenuation instrument, provide the source, filter path, counting geometry and expected operating environment.

Frequently Asked Questions
What is SP102 Plastic Scintillator used for?
Why is SP102 usually thin?
What is the emission wavelength of SP102?
Is SP102 hygroscopic?
What information is needed for an SP102 quotation?
Does SP102 sheet thickness specify flatness after mounting?
No. Thickness tolerance, free-sheet shape and the shape of a mounted sheet are separate requirements. For a thin-sheet design, show the support arrangement, unsupported area and any required mounted clearance. State whether dimensional inspection is to be performed before or after mounting, and ask which conditions can be included in the component quotation.
Should an SP102 drawing include the frame opening as well as sheet dimensions?
Yes. Mark the sheet outline, intended active area, frame opening and mounting margins separately. Identify any area covered by supports, wrapping or the optical interface. This allows the component drawing to be checked against the measurement aperture instead of assuming that the entire sheet outline remains exposed in the assembled instrument.
