The SureLock™ ROUSB Series is designed as a compact, single‑frequency, wavelength‑stabilized laser module for OEM integration into cost‑sensitive instruments that require high coherence, such as particle sensing, interferometry, metrology, and HeNe replacement systems. The module integrates the laser diode, TEC temperature control, and constant‑current driver into a single cylindrical package, minimizing external electronics and integration effort. The lower cost ROUSB Series provides more limited functionality: - Single‑frequency operation with narrow linewidth (typically 150–300 MHz) depending on diode - Excellent wavelength stability using SureLock™ external‑cavity stabilization These characteristics support long coherence length, stable interference fringes, and repeatable phase measurements required in interferometric and particle characterization systems. SureLock™ technology uses an external cavity with a stabilizing element to lock the laser wavelength, maintaining spectral performance across 0–100% operating power and over temperature. For OEM systems, this means: - Reduced calibration drift over time - Improved unit‑to‑unit consistency - Stable fringe spacing in interferometric measurements Standard ROUSB wavelengths include: - 633 nm (40–70 mW) - 638 nm (up to 120 mW) - 658–660 nm (≈35 mW) - 785 nm (80–100 mW) Multiple OEM SKUs are available, including variants with optical isolators or single‑mode fiber pigtails, depending on system requirements. For low‑cost OEM instruments, the RO‑USB reduces BOM and integration cost by: - Eliminating the need for external laser drivers and TEC controllers - Providing USB‑based digital control instead of custom analog electronics - Offering HeNe‑like performance in a compact diode‑based solution OEMs can select from: - Free‑space collimated output - Single‑mode PM fiber‑coupled output - Optional built‑in optical isolator Fiber‑coupled versions are recommended when beam delivery, alignment stability, or modular optical layouts are required. The ROUSB Series operates from: - 3.3–5 VDC input (model‑dependent) - <3 A operating current (max) Control options include: - USB virtual COM port for digital control and monitoring - TTL on/off input for simple modulation or safety control Yes. The ROUSB can operate in stand‑alone mode using stored current and temperature setpoints. USB communication is optional and typically used during: - Factory configuration - Calibration - Advanced diagnostics No. In its OEM configuration, the RO‑USB Series is intended solely as an OEM component and does not comply with CDRH 21 CFR requirements when operated as a standalone product. Regulatory compliance is the responsibility of the final instrument manufacturer. An optional configuration with keyswitch is available for CDRH 21 CFR 11 requirements. The ROUSB Series is well‑suited for volume deployment due to: - Fixed, factory‑aligned optics - Digitally repeatable settings - Stable wavelength performance across units - Availability of OEM SKUs without keyswitches The ROUSB Series is ideal for: - Low‑cost interferometers - Particle sizing and counting systems - Compact metrology tools - Embedded HeNe replacement platforms - OEM sensing and analytical instruments It bridges the gap between simple diode modules and higher‑cost stabilized laser systems, offering coherence where it matters most.

ORCA is a THz-Raman™ crystallinity meter that uses a scanning laser beam to detect and identify low concentrations of specific polymorphs of Active Pharmaceutical Ingredients (APIs) within complex mixtures. By probing low-frequency lattice vibrations that are highly sensitive to crystal structure, ORCA enables reliable detection of targeted polymorphic forms even at very low concentrations. This rapid, non-destructive technique requires little to no sample preparation and provides a powerful complement to PXRD for solid-form characterization. ORCA supports polymorph screening, crystallinity analysis, and pharmaceutical quality control, enabling fast identification of crystalline phases directly within heterogeneous samples.

WALDO builds on the WPS high-throughput THz-Raman™ screening platform by adding flexible measurement geometries for a wider range of microplate formats. WALDO supports laser scanning through transparent well plates as well as top-down excitation for opaque plates, including stainless steel and Kapton plates commonly used for PXRD experiments. This dual-mode capability allows researchers to perform rapid polymorph screening and crystallinity analysis across different sample holders while leveraging the sensitivity of low-frequency THz-Raman™ spectroscopy to probe crystal lattice structure and molecular composition.

SureLock™ wavelength-stabilized laser diodes and modules incorporate our ultra-narrowband VBGs, forming an external cavity using TruSet to precisely lock the laser’s wavelength to the needs of the application. This enhances spectral brightness and optical performance stability across the entire power range and extended temperature conditions. The extremely short external cavity offers superior mode selection and a smaller footprint than Littrow or Littman cavity designs while reducing the spectral bandwidth of a typical laser by an order of magnitude. With fast warm-up times, flexible power options, and consistent performance, these lasers are ideal for demanding applications such as analytical instruments. Available as modules or components, SureLock® lasers offer flexibility for seamless development and system integration. Applications - Raman spectroscopy - Holography - HeNe replacement - Particle characterization - Analytical instrumentation - Speckle interferometry - Metrology and inspection
