Our Optical Architecture
How we achieve sub-nanometer resolution in a compact form factor by rethinking the symmetric crossed Czerny-Turner design.
Combating Spherical Aberration
In traditional compact spectrometers, short focal lengths introduce severe spherical aberration and coma, distorting the spectral lines on the detector array and degrading resolution.
Spectroa utilizes a proprietary asymmetric mirror configuration and toroidal focusing mirrors to physically correct for these aberrations across the entire focal plane, rather than relying on software deconvolution.
Thermal Stability
Our optical benches are machined from a single block of material, preventing thermal drift caused by mismatched expansion coefficients found in bolted assemblies.
Blazed Gratings
We use holographic blazed gratings optimized for specific wavelength regions, maximizing optical throughput and dramatically reducing stray light compared to ruled gratings.
Slit Dynamics
Precision photolithographic slits define the entrance aperture, ensuring uniform illumination of the collimating mirror and exact resolution characteristics.
