... with reflecting superposition optics. These eyes view the world through an orbital hood that is 80–90% as transparent as seawater across visible wavelengths (400–700 nm). Through electroretinography and microspectrophotometry, we found the eyes of A. heterochaelis have a temporal sampling rate of >40 Hz...

... visual system. Design-based stereology and microspectrophotometry were used to assess spatial resolving power and spectral sensitivity of saltwater ( Crocodylus porosus ) and freshwater crocodiles ( Crocodylus johnstoni ). Both species possess a foveal streak that spans the naso-temporal axis...

... that all show minimal UV reflectance. Here, we determine the cone photoreceptor spectral sensitivities and opsin expression of the two lineages, to test whether they differ, particularly in the UV wavelengths. Using microspectrophotometry on retinal cone photoreceptors, we identified a long-wavelength...

... it an ideal candidate for intraspecific differences in spectral sensitivity. Here, the visual pigments of P. elegans were fully characterised through molecular sequencing of five visual opsin genes and measurement of their absorbance spectra using microspectrophotometry. Three of the genes, LWS , SW1 and SWS2...

... of the chromophore bound to opsin proteins was investigated using high performance liquid chromatography. The opsin genes were then cloned and sequenced, and the absorption spectra of different types of cones were obtained by microspectrophotometry. Two green (EJ-RH2-1, EJ-RH2-2) and one red (EJ-LWS) cone opsin...

... among bowerbird species that occupy different visual habitats and are highly diverged in plumage and decoration colour displays, which are important in mate choice and possibly reproductive isolation. Microspectrophotometry of violet-, short-, medium- and long-wavelength-sensitive cones revealed...

... investigated the white and glass scales with transmission and scanning electron microscopy, microspectrophotometry and imaging scatterometry, and we found that the glass scales are uniquely structured and approximate ideal thin films. The transmittance and reflectance spectra of single scales could be well...

Microspectrophotometry was used to determine the wavelengths of spectral sensitivity of the photoreceptors at four developmental stages: larval, post-settlement, juvenile...

... of SWS1 opsin expression in the retina of adult rainbow trout, perhaps via a reverse process to that occurring in the juvenile, has not been investigated. Here, we used in situ hybridization with species-specific riboprobes and microspectrophotometry on rainbow trout retina to show that: (1) single cones...

North-American species ( Uca pugnax and U. pugilator ), one species from the Indo-West Pacific ( U. vomeris )and the only Eastern-Atlantic species ( U. tangeri ) of fiddler crabs using in situ microspectrophotometry of frozen sections of dark-adapted eyes. Only one spectral class of visual receptor...

In this study, microspectrophotometry was used to measure the absorption spectra of cone oil droplets in chickens...

... the potential for colour vision. Using microspectrophotometry, we show that the retinae of the giant shovelnose ray ( Rhinobatos typus ) and the eastern shovelnose ray ( Aptychotrema rostrata ) contain three spectrally distinct cone visual pigments with wavelengths of maximum absorbance(λ max ) at 477, 502...
