Spectroscopy instruments

High-resolution echelle spectrometers

Compact, cross-dispersed spectrographs designed to capture fine spectral detail across a broad wavelength range.

01 / INSTRUMENTS

Visible and near-infrared spectroscopy

Our echelle spectrometer platform combines dispersive optics, a detector, and a lightweight optical structure. Development focuses on visible and near-infrared measurements for laboratory and industrial instruments.

02 / INTEGRATION

Custom spectrometer configurations

Discuss optical layouts, slit and fiber interfaces, detector integration, calibration, and packaging for your measurement. Wavelength coverage, resolving power, and throughput are specified for each configuration.

03 / APPLICATIONS

Research and industrial spectroscopy

Development applications include atomic emission studies, laser and light-source characterization, materials research, and optical diagnostics for manufacturing and process monitoring.

The echelle platform is at the prototype and development stage. Contact Opticco for current measured performance, configuration options, and availability.

Custom optical engineering

Optical design, prototyping & manufacturing

Custom optical arrangements and assemblies built around your beam path, mechanical envelope, and measurement requirements.

DESIGN

Custom optics arrangements

Optical system layout and optomechanical design for mirrors, lenses, gratings, prisms, detectors, and fiber interfaces. We develop arrangements for spectroscopy, beam delivery, and optical instrumentation.

PROTOTYPE

Optical assembly prototyping

CAD development, custom mounts, composite structural components, instrument housings, assembly, and alignment. Prototype iteration connects the optical design to hardware that can be characterized.

MANUFACTURE

Custom optical assemblies

Custom fabrication and assembly of optical structures and instruments, with electronics and calibration integration where required. Project scope, quantities, acceptance tests, and lead times are agreed during the technical review.

From a custom optical subassembly to an integrated spectrometer, share your requirements to discuss a design, prototyping, or manufacturing project.

Lightweight precision structures

Low-CTE optical assemblies

Low coefficient of thermal expansion (CTE) structures help reduce changes in optical geometry as temperature varies. Opticco develops carbon-fiber optical frames using pultruded members and custom PPS-CF components for lightweight, thermally stable instrument designs.

CharacterizationAlignment, stability, and prototype testing

Assembly stability depends on material orientation, joints, geometry, and temperature conditions. Thermal performance is evaluated for each design.

Aerospace development

CubeSat spectrometers & space optical assemblies

Custom optical payload development for small satellites, space telescopes, and cameras that need added spectral measurement capability.

Development capability

CubeSat spectrometers

Compact spectrometer concepts for CubeSat and small-satellite payloads, with optical design and packaging tailored to the available volume, mass, power, and required spectral performance.

Project-specific qualification

Space-ready optical assemblies

Design and prototyping toward space-ready optical assemblies, including lightweight low-CTE frames and payload mounts. Space readiness is a qualification goal defined by each mission's launch and operating environment.

Development concept

Camera-guided point spectroscopy

Image-guided spectroscopy concepts let a user select a point in a camera view and acquire its spectrum. A scanning implementation could extend this approach to spatially resolved spectral mapping and hyperspectral imaging.

These aerospace concepts are in development; flight qualification has not been established. Discuss mission-specific requirements for vibration, thermal-vacuum operation, outgassing, and other environmental testing.

Technology in development

Computational HDR spectroscopy

Variable-slit acquisition and synchronized exposures are being developed to combine complementary measurements of bright and weak spectral features.

  • 01
    Active variable optical slit

    Controlled slit settings and exposure timing provide complementary spectral measurements.

  • 02
    Multi-exposure reconstruction

    Research into computational methods for combining measurements with different slit widths and exposure times.

  • 03
    Experimental validation

    Development includes testing dynamic range, spectral detail, calibration, and measurement repeatability.

In development

FTIR instruments & precision optical translation

Fourier-transform infrared (FTIR) instrument development includes translating-mirror mechanisms, electromagnetic actuation, and levitated-stage research for interferometric scanning.

Integrated engineering

Optomechanics, electronics & calibration

Custom PCB design, embedded control, actuator drivers, precision slit mechanisms, wavelength calibration, and spectral acquisition software support the optical instrument as an integrated system.

Questions about custom optical projects

Can Opticco design and manufacture a custom optical assembly?

Opticco's project scope includes custom optical arrangements, optomechanical design, prototype fabrication, assembly, alignment, and custom manufacturing. Contact us with your optical layout or measurement goal to discuss the components, integration work, quantities, and testing your project needs.

What are low-CTE optical assemblies used for?

Low-CTE assemblies are designed to reduce thermal expansion in structures that position optical components. They can support alignment stability in spectrometers, interferometers, and other precision instruments. The performance of the complete assembly depends on its materials, joints, orientation, and operating conditions.

Are CubeSat spectrometers and space-ready assemblies available?

Opticco welcomes custom development inquiries for CubeSat spectrometers and space optical assemblies. These are development capabilities, and flight qualification has not been established. Availability and the qualification plan depend on the proposed payload and mission requirements.

What should I send for a custom spectrometer or optics project?

Describe the measurement, wavelength range, desired spectral resolution, light source or fiber interface, detector requirements, size and mass limits, operating environment, quantity, and schedule. Early concepts are welcome; we can discuss which requirements should guide the first prototype.
