MARKET INSIGHTS: Engineering and finance can partner to drive product development
… aspheres into their systems at a reduced cost. The product line aims to provide the performance of an asphere at the price of an achromat . In the photonics industry, R&D is increasingly tied to the factory floor and can be classified as projects that accomplish …

OPTICS FABRICATION: Off-the-shelf edge-blackened optics speed system integration
… resorting to custom fabrication. A single- achromat example While many custom optical systems ..... feature. An example based on a single achromat demonstrates the benefit of using edge ..... the stray-light behavior of a single achromat in a specific, yet common lighting geometry …

Bern Optics offers achromats and doublets in diameters down to 0.20 mm
… today announced the availability of submillimeter achromatic lenses as small as 0.20 mm diameters. The most common type of achromat is an achromatic doublet, a compound lens consisting of two elements cemented together. These precision, micro-miniature …

Hybrid lenses offer high performance at low cost
… hybrid lenses A conventional refractive achromat consists of two different glass types ..... In addition, the weight of a hybrid achromat is typically only one-half to one-third that of the corresponding conventional achromat . Because one can eliminate expensive …

IR OPTICS: Ultrabroadband optics image from visible to longwave IR
… derivation is a maximization of the dispersive volatility and as such should ideally be matched to its complementary material in the achromat : f"(λ) = lim h→0 ([f' (n(λ i+h i ))]/h In fact, this type of mathematical analysis is well-suited …

SIGNAL PROCESSING: Tilted grating produces true time delay for RF photonics
… fs for different mirror angles, which is one to two orders of magnitude better than that for chirped FBG delay lines. The achromat introduced some spherical aberration into the system, as determined by taking data at two focal positions—the paraxial …

MEDICAL OCT: Ultra-high-resolution optical coherence tomography gets adaptive-optic ‘glasses’
… We inserted an achromatizing elemement into the same optomechanical mount tube as the collimating objective (a commercial achromat ). This ensures that the achromatizing element is well centered on the system’s optical axis and pupil, and that no extra …
