As part of a color control program, brand owners and designers use spectrophotometers to specify and communicate color, and manufacturers use them to monitor color accuracy throughout production.The Ocean Optics Red Tide Spectrometer is a preconfigured, off-the-shelf spectrometerwhere all of the optical bench options such as grating, and entrance slit size are alreadyselected. The red Tide can be used with various Ocean optics spectrometer accessories, lightsources and sampling optics to create application-specific systems for various absorbance,reflection and emission applications.The Red Tide is low-cost and has a small footprint, making it ideal as a general purposeinstrument for budget-conscious teaching and research labs. It has a wavelength range of350–1000 nm and uses adetector with 650 active pixels; that’s 650 data points in one full spectrum, or one data pointper nanometer.Data programmed into a memory chip on each Red Tide includes wavelength calibrationcoefficients, linearity coefficients, and the serial number unique to each spectrometer. Ourspectrometer operating software simply reads these values from the spectrometer — a featurethat enables hot swapping of spectrometers among computers.The Red Tide Spectrometer connects to a computer via the USB port. When connectedthrough a USB 2.0 or 1.1, the spectrometer draws power from the host computer, eliminatingthe need for an external power supply. The Red Tide also interfaces to Pasco’s Xplorer GLX,a unique combination of datalogger and lab analysis tool that eliminates the need for acomputer. The Red Tide, like all USB devices, can be controlled by our SpectraSuite software, acompletely modular, Java-based spectroscopy software platform that operates on Windows,Macintosh and Linux operating systems.", "price": 0.0, "discountamount": 0.0, "currencycode": "INR", "priority": 1000000, "isfreeshipmentavailable": false, "shipmentduration": 1, "_keywords": null, "isarchived": false, "isavailable": true, "applicationid": null, "productindex": 265, "imageuri": "https://productimages.withfloats.com/actual/6916bdc3f37ccc300a1acb43.jpeg", "tileimageuri": "https://productimages.withfloats.com/tile/6916bdc3f37ccc300a1acb43.jpeg", "images": null, "totalqueries": 0, "gpid": null, "groupproductid": null, "createdon": "2025-11-14T05:27:30.705Z", "updatedon": "2025-11-14T05:27:30.705Z", "buyonlinelink": null, "producturl": "http://WWW.COMTEKSCIENTIFIC.IN/products/color-spectrophotometer-usb650-vis-nir/265", "availableunits": -1.0, "iscodavailable": false, "isprepaidonlineavailable": false, "maxcodorders": 0, "maxprepaidonlineorders": 0, "uniquepaymenturl": null, "brandname": "MARUTEK ", "category": "Color Spectrophotometer", "tags": [], "variants": false, "keyspecification": null, "otherspecifications": null, "pickupaddressreferenceid": null, "paymenttype": "None", "producttype": "products", "hsncode": null, "gstslab": 0.0, "isnotforsale": false }, { "_id": "6902f12d0c31b1295dc50853", "fptag": "COMTEKSCIENTIFICINSTRUMENTS", "merchantname": null, "customwidgets": null, "externalsourceid": null, "name": "WP-NIR1-C-S-yy", "description": "The 900-2500 nm wavelength range just beyond the visible offers a tremendous wealth of information about the composition of materials that can be used for material identification, quality control, process monitoring, and many medical applications – particularly when combined with the power of chemometrics.
