Description Specification

Feature	Fiber Optic Cable	Auxiliary Power Supply	Signal-to-Noise Ratio	Cable Swap-ability	Recommended Use Case
FieldSpec	Factory-installed, not field-replaceable	Required for contact probes or low-light conditions	Best (direct optics to diffraction gratings)	Requires factory service for cable replacement	Best signal-to-noise ratio required. Reliable, stable factory installation of fiber optic cable. Users are mindful of the fiber optic cable.
TerraSpec	User-connected with SMA 905 connector	Required for contact probes or low-light conditions	Sufficient (signal loss at jumper cable connection)	Field swappable for convenience in rough and remote situations	Mining environments with rough handling and need for easy cable replacement. Repeated user check of fiber optic cable at SMA connection acceptable.
LabSpec	User-connected with SMA 905 connector	Required for contact probes or low-light conditions	Sufficient (signal loss at jumper cable connection)	Field swappable for convenience in rough and remote situations	Controlled lab settings with potential for varied measurement setups. Start-up user check of fiber optic cable at SMA connection acceptable.

FieldSpec

Best for: Users requiring maximum sensitivity, ideal for outdoor and remote sensing applications.

Superior Signal-to-Noise Ratio: Twice as sensitive as TerraSpec and LabSpec, making it the best choice for working with limited natural light sources like sunlight.
Permanent Fiber Optic Cable: Factory-installed to eliminate signal loss at junction points, ensuring optimal performance.
Recommended for Sunlight Use: Essential for reliable data collection under natural light.
Ideal for Remote Sensing: Used for ground-truthing overflight sensors, matching satellite data, and ensuring accurate spectral measurements under varying environmental conditions.

TerraSpec

Best for: Users requiring maximum sensitivity, ideal for outdoor and remote sensing applications.

User-Replaceable Fiber Optic Cable: SMA 905connector allows quick cable replacement in the field, minimizing downtime.
Use with Artificial Light Sources: Can compensate for lower sensitivity with artificial light sources.
Bifurcated Cable Compatibility: Ideal for precise spot measurements in mining applications.
Geology & Mining Applications: Designed for enclosed formations, core logging, and reconnaissance sampling.

LabSpec

Best for: Users requiring maximum sensitivity, ideal for outdoor and remote sensing applications.

Cost-Effective Alternative: Provides a lower-cost solution for those not requiring FieldSpec’s high-end performance.
Artificial Light Advantage: Lower signal-to-noise ratio can be compensated with powerful artificial light sources.
User-Replaceable Fiber Optic Cable: Features SMA 905 connector for easy cable replacement and flexible light source options.
