WE ARE SAGITTAL OPTICS, SCROLL TO DISCOVER!
WELCOME TO SAGITTAL
We engineer, craft, and deliver cutting-edge optical solutions for visionary enterprises.
ABOUT US
Sagittal Optics offers optical and optomechanical engineering services ranging from systems design from scratch to prototype manufacturing endorsed by 25 years of experience. As an enhancement, layouts could comprise our in-house analytical material selection tool and the implementation of aspherical/freeform optical surfaces.
Our team is connected to both cutting-edge technology and manufacturing industry to produce optical designs adapted to different environments. They extend from miniaturised mass-use device systems with demanding requirements for robustness to systems working in challenging conditions such as space or large aperture optics for big astronomical telescopes.

OUR SERVICES
Optical design
Designing, reviewing and performing trade-offs of optical systems from scratch targeting custom criteria/merit function of performance evaluation (i.e. optimizing resolution, contrast, throughput, alignment procedures, envelope limitations, cost requirements, athermalization or zooming features).
Optimization of the system and optical simulation scripting
Refinement and enhancement of pre-established systems to modulate performance or reduce costs. Aspherization and free-form shaping of surfaces for enhancing optical performance. Definition of compensators to loosen sensitivities and tolerances. Zoom systems optimization.
Optomechanical design
Expertly blending precision optics with robust mechanical engineering, our optomechanical design expertise ensures the seamless integration and durability of your optical systems.
Optomechanical simulation
FEA-based mechanical analyses covering thermal, structural and modal evaluations of optomechanical systems. Our capabilities include prediction of temperature distributions, assessment of mechanical behaviour under various load cases and analysis of dynamic responses. We provide detailed insights to optimise designs in terms of reliability and performance.
Sensitivity and tolerance analysis
Sensitivity analysis with debugging of worst offenders according to alignment, integration and manufacturing tolerances with final polynomial fitting. Tolerance allocation and top-down/bottom-up error budgets through Inverse sensitivity/MonteCarlo analyses. Statistical analysis to establish cumulative probability curves to estimate non-compliance percentages. Analysis of the cost-benefit ratio between system performance and sensitivities adjustment.
AIV of optical systems
Our optical and optomechanical designs are meticulously crafted with a focus on optimizing the assembly, integration and verification stages to ensure reliability. This entails an initial review of the design requirements to guarantee their measurability, precision and compliance with necessary equipment. Our experts have a strong background in theory of optical aberrations and its role in optical alignment, as well as in assorted alignment equipment, techniques and diagnostic tools.
Stray light and ghosts analysis
Non-sequential simulation assessing stray light minimization, ghosting, light clashes, baffling, vignetting and illumination and specially in highly responsive systems such as laser applications or infrared systems.
Diffraction analysis
Wavefront tracing allowing modelling of diffractive aspects of optical systems. Evaluation of the effects of the stop or lenses aperture, including spatial filtering, Gaussian laser beams, calculation of diffractive PSF or MTF and performance in the region limited by the detector resolution.
Gaussian optics
Optical design of systems working with sources following Gaussian transmission equations (lasers) where the use of diffraction-based propagation techniques is required in conjunction with geometrical ray tracing.
Specification and procurement of optical components
Broad portfolio of suppliers of customised precision components, world-wide based, also offering a wide range of finishes and qualities. Procurement specifications exchange based on ISO standards. Acceptance plan definition and technical acceptance of custom components, parts, and assemblies.
Prototyping development
Development of opto-mechanical prototypes and proof-of-concept. Assessment of feasibility for large-scale manufacturing assuring low risk and cost minimization.
