Biospherical Instruments

What Biospherical Instruments does

Biospherical Instruments, Inc. (BSI) is a San Diego-based designer and manufacturer of scientific instrumentation specializing in high-precision optical and environmental sensing for aquatic, atmospheric, and terrestrial applications. Founded in 1977 and operating as a subsidiary of AdaptiSense since the 2021 acquisition, the company's core technology is its proprietary microradiometer detector architecture — hybrid detector arrays combined with hard-coat multicavity interference filters — which underpins a portfolio spanning single-channel PAR radiometers (Q-Series, MPE/MPS/MLS, AMOUR), multispectral arrays (XRR/XRL/XRE, GUVis-3511), the C-OPS Compact Optical Profiling System and C-PrOPS ROV upgrade, the C-AIR/BioAIR airborne radiometer, and the BioCLEAR biofouling-control line. BSI's product set has expanded since 2021 into Passive Acoustic Monitoring (RESEA, SYLENCE-LP, TRIPOD via the RTsys partnership), micro AUV distribution (NemoSens, COMET 300 via RTsys), and micro gas spectrometry (MicroFlow NDIR via Micro-Hybrid), with the Gino IoT hyperspectral spectrometer as a further in-house addition.

BSI serves a customer base concentrated in U.S. federal science and defense agencies (NASA, NOAA, NSF, ONR, SPAWAR, U.S. Antarctic Program), allied government agencies (KHOA via OceanTech), and academic / non-profit institutions (Scripps Institution of Oceanography, NDACC, Cousteau Society). Revenue is generated primarily through quote-based hardware sales of sensors, profilers, AUVs, and acoustic systems, supplemented by NIST-traceable calibration and characterization services offered on a contract basis to third parties, and by repair/recalibration revenue via RMA. Software is bundled at no additional charge. Distribution is hybrid: direct sales cover the US, Canada, and Mexico, while international markets are reached through qualified regional representatives and exclusive resellers (OceanTech for South Korea, RTsys/Neotek for Europe). BSI also acts as the North American distributor for RTsys AUVs under a three-year contract, creating a two-way channel relationship.

Revenue model

1. Sensor & Instrument Hardware Sales: Direct sale of radiometers, multispectral arrays, single-channel sensors, biofouling control systems, AUVs, and acoustic recorders through quote-based pricing to scientific, defense, and industrial customers. Sales handled in-house for US/Canada/Mexico and via international representatives elsewhere.
2. Calibration, Characterization & Laboratory Services: Revenue from NIST-traceable calibration services (irradiance, radiance, spectral response, directional response, temperature/pressure/tilt, immersion coefficient) for BSI instruments and third-party sensors. Calibration facilities available to third parties on a contract basis.
3. Software Licensing (Bundled): Data acquisition software (uProfile, uLogger, LoggerLight, Logger2100, Logger2150, µLoggerLight) supplied with instruments at no extra charge. Software distributed via direct download (Dropbox).
4. Repair & Recalibration Services (RMA): Revenue from Return Material Authorization (RMA) repair and recalibration services for BSI instruments, with international customers shipping via DHL/UPS/FedEx with harmonized code 9801.00.1012.

Core offering

Biospherical Instruments designs, manufactures, and supports scientific optical and environmental sensors, multi-channel radiometers, underwater profiling systems, biofouling control modules, and AUV/ROV deployment platforms used for aquatic, terrestrial, and airborne observations. The portfolio also includes passive acoustic monitoring instruments, micro gas spectrometers, and an in-house NIST-traceable calibration and engineering services facility that supports both BSI products and third-party sensors.

Product overview

Biospherical Instruments (BSI) operates a portfolio-plus-platform architecture rather than a single unified product: at its core sits the microradiometer-based optical sensing platform — spanning single-channel radiometers (the Q-Series PAR, MPE/MPS/MLS-PAR, AMOUR sensors), multispectral arrays (XRR with XRL/XRE configurations and the GUVis-3511 ground radiometer), and the C-OPS Compact Optical Profiling System — that all leverage BSI's microradiometer detector technology. Around this core, BSI has built deployment and integration modules: the BioSHADE shadowband and BioGPS accessories; the C-PrOPS ROV thruster upgrade that turns a C-OPS profiler into a maneuverable ROV; the BioMAST deployment system and BioCLEAR biofouling control for long-term in-water deployments; the C-AIR/BioAIR airborne radiometer for NASA flight operations; and new product families acquired or partnered into the line — the RTsys NemoSens and COMET 300 micro AUVs (resold in North America), the RESEA / SYLENCE-LP / TRIPOD acoustic recorders integrated through the RTsys (France) PAM partnership, and the Gino IoT micro spectrometer and MicroFlow NDIR gas spectrometers (added through the Micro-Hybrid partnership). Custom engineering services and a NIST-traceable calibration and characterization laboratory underpin the entire portfolio.
