DeltaDiode
Vue d'ensemble
La première source laser à diode picoseconde/100 MHz équipée de têtes interchangeables et d’une interface USB
Les sources laser DeltaDiode utilisent la technologie des diodes laser et des LED pour générer des impulsions optiques de courte durée, sur de très vastes plages de cadences de répétition et de longueurs d’onde. Des impulsions de 50 ps peuvent ainsi être générées à une cadence de répétition de 100 MHz. Bénéficiant de fonctions sophistiquées telle que les têtes interchangeables à chaud, le pilotage par USB et une intégration logicielle complète, la gamme DeltaDiode délivre les meilleures performances disponibles à ce jour, sous le format le plus convivial.
La gamme DeltaDiode comprend un contrôleur et une série de têtes interchangeables à LED ou diode laser, ainsi qu’un ensemble d’accessoires pratiques tels que des adaptateurs fibre et des filtres. La plupart des têtes à diode laser peuvent fonctionner en mode continu et pulsé (en option).
Applications
- Sources d’excitation pour TCSPC
- Imagerie des durées de vie de fluorescence (FLIM = Fluorescence Lifetime Imaging)
- Spectroscopie de fluorescence
- Test de réponse des détecteurs
- Cryptographie quantique
Performances
DD-405L fonctionnant à 100 MHz, avec une durée d’impulsion < 55 ps. L’après-impulsion est caractéristique des détecteurs à plaques à microcanaux (MCP = Micro-Channel Plate).

- Spectral FWHM in pulsed mode typically <10nm, in CW mode <2nm.
- Pulse width refers to optical pulse duration measured at 20MHz repetition rate and default settings; in TCSPC the prompt FWHM is also a function of detector TTS.
- Peak power and average power are measured at maximum repetition rate and are typical values when new, peak power is calculated.
- To calculate typical pulse energy, divide average power (in Watts) by maximum repetition rate e.g. for DeltaDiode-375L pulse energy is 20pJ.
- To specify fibre launcher add –F suffix. To specify CW operation (where available) add –CW suffix.
- Specifications and appearance are subject to change without notice.
Additional features:
- Active stabilization of diode temperature in range 20ºC to 40ºC (user programmmable)
- Aspheric collimation lens, adjustable for focus and beam trajectory
- Vertically polarised output
- Mounting: 35mm bayonet coupling permits quick interchange, free rotation of beam polarisation, and ambient light exclusion; M4 threaded hole provided for optical table mounting.

Software
DeltaDiode is supplied with control panel software as shown below. For customers with HORIBA Scientific TCSPC systems, DeltaDiode may alternatively be controlled by DataStation for automatic selection of repetition rate to match the fluorescence lifetime of the sample under investigation. 32-bit and 64-bit drivers are provided and the control panel software operates on all versions of Windows from XP onward. Note that a PC connection is not required to operate DeltaDiode as all parameters may be accessed via its front panel LCD display. 
Accessoires
A range of accessories are available for use with DeltaDiode heads. Accessories are stackable so several may be used simultaneously.
| Bandpass filters are available at most wavelengths |
| A mechanical shutter is included as standard on Class 3B laser heads and is available as an option for use with other heads. |
| Fiber launchers are available in three wavelength regions: <400nm, 400-600nm and >600nm. Please note that the fiber shown is not included. To specify a DeltaDiode laser with a pre-aligned launcher simply add the "-F" suffix to the order code. Fiber launchers may also be ordered separately and fitted to laser heads retrospectively. |
