Avantes AvaSpec-HSC1024x58TEC-EVO High-Sensitivity Research-Grade Fiber Optic Spectrometer

Overview

The Avantes AvaSpec-HSC1024x58TEC-EVO is a high-performance, research-grade fiber optic spectrometer engineered for demanding spectroscopic applications requiring both exceptional sensitivity and spectral resolution across the ultraviolet, visible, and near-infrared (UV-VIS-NIR) range (200–1160 nm). Its optical architecture employs a symmetrical Czerny-Turner design with a 100 mm focal length and numerical aperture of 0.13—optimized to maximize light throughput while minimizing aberrations. At its core lies a back-illuminated, linear CCD detector array (1024 × 58 pixels) integrated with single-stage thermoelectric cooling (TEC), enabling stable dark-current suppression and extended integration times up to 60 minutes—critical for low-light measurements such as fluorescence, Raman scattering, or weak-emission plasma diagnostics. The spectrometer utilizes the AS7010 electronics platform, featuring a 16-bit analog-to-digital converter operating at 250 kHz sampling rate, which ensures minimal read noise and supports high-fidelity signal digitization essential for quantitative spectral analysis under variable illumination conditions.

Key Features

• High-sensitivity HSC optical platform with 100 mm focal length and NA 0.13 for superior étendue and throughput
• Back-illuminated 1024 × 58-pixel CCD detector with integrated single-stage TEC cooling (–10 °C typical stabilization)
• Configurable spectral resolution from 0.2 nm to 7 nm (FWHM), dependent on grating line density and entrance slit width (25–500 µm options)
• Maximum sensitivity of 445,000 counts per µW per millisecond—enabling detection of sub-nanowatt optical signals
• Signal-to-noise ratio of 1200:1 (at full well capacity) and dynamic range of 40,000:1, supporting wide-intensity-range measurements without gain switching
• Dual high-speed communication interfaces: USB 3.0 (5 Gbps) and Gigabit Ethernet (1 Gbps), ensuring deterministic data acquisition and remote operation in networked lab environments
• HD-26 digital I/O interface with 3 bidirectional digital lines, 2 analog inputs, 2 analog outputs, trigger/synchronization support, and pulse-laser control capability
• Modular configuration options including interchangeable slits, 12 standard gratings (246–2400 lines/mm), and customizable wavelength coverage

Sample Compatibility & Compliance

The AvaSpec-HSC1024x58TEC-EVO is compatible with standard SMA 905 fiber-optic interfaces (e.g., 50–1000 µm core diameter fibers), enabling seamless integration with external light sources (Xe/Hg lamps, LEDs, pulsed lasers), sample holders (cuvette stands, integrating spheres, fiber probes), and accessories (optical filters, polarization optics, collimators). Its optical design supports both free-space and fiber-coupled configurations. From a regulatory standpoint, the instrument complies with CE marking requirements (EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU). While not inherently FDA 21 CFR Part 11–compliant as a standalone device, its data output format (ASCII, CSV, binary) and timestamped metadata generation are fully compatible with validated LIMS and ELN systems used in GLP/GMP environments. Traceable calibration options—including NIST-traceable wavelength and radiometric calibration—are available upon request to meet ISO/IEC 17025 laboratory accreditation requirements.

Software & Data Management

The spectrometer ships with AvaSoft-Basic, a cross-platform (Windows/macOS/Linux) application providing real-time spectrum acquisition, baseline correction, peak identification, and export to industry-standard formats (CSV, TXT, SPC). For advanced users, the Avantes SDK (C/C++, Python, MATLAB, LabVIEW, .NET) enables full programmatic control of all hardware parameters—including integration time, averaging, ROI selection, and I/O pin states—facilitating custom automation workflows and integration into larger experimental platforms. All acquired spectra include embedded metadata (timestamp, integration time, grating ID, slit width, temperature), supporting FAIR (Findable, Accessible, Interoperable, Reusable) data principles. Raw data files are stored without proprietary compression, ensuring long-term archival integrity and third-party software compatibility (e.g., Origin, Igor Pro, Python’s specutils).

Applications

This spectrometer is routinely deployed in academic and industrial research settings where high photon efficiency and measurement reproducibility are critical. Typical use cases include: steady-state and time-resolved fluorescence quantum yield determination; low-frequency Raman spectroscopy of carbon nanomaterials and 2D semiconductors; UV absorption kinetics of photochemical reactions; NIR reflectance profiling of pharmaceutical tablets; plasma emission monitoring in semiconductor process chambers; and hyperspectral imaging system calibration. Its extended UV response (down to 200 nm) and optional deep-UV optimized gratings make it suitable for ozone monitoring and synchrotron beamline diagnostics. The combination of thermal stability, low-noise electronics, and flexible triggering ensures robust performance in synchronized pump-probe experiments and lock-in detection schemes.

FAQ

What is the minimum detectable irradiance level for this spectrometer?
The theoretical limit depends on integration time, slit width, and grating selection—but under optimal conditions (500 µm slit, 300 l/mm grating, 60 s integration), detection thresholds below 10⁻¹⁵ W/cm²/nm are achievable in the visible range.
Can the AvaSpec-HSC1024x58TEC-EVO be used in vacuum or controlled atmosphere environments?
The housing is not hermetically sealed; however, it may be operated in dry nitrogen-purged enclosures. Optional O-ring sealed versions with feedthrough connectors are available for specialized environmental integration.
Is radiometric calibration included with purchase?
Standard units ship with wavelength calibration only. NIST-traceable radiometric calibration (irradiance or radiance) is offered as an optional service with documented uncertainty budgets.
How does the TEC cooling affect long-term stability during multi-hour acquisitions?
The single-stage cooler maintains detector temperature within ±0.1 °C over 8-hour periods when ambient temperature is stable, minimizing dark current drift and pixel-to-pixel responsivity variation.
Are firmware updates and driver support provided post-purchase?
Yes—Avantes provides free lifetime firmware and driver updates via its official support portal, including backward-compatible API revisions and security patches for network-connected units.
