By simplification of the optical engine and\nspecific sensor, the further miniaturized spectrometer is achieved.\nExternal MB type of PH Series can be chosen to enhance heat\ndissipation. The compact size and various of screw holes is very flexible\nfor system integration.\nPH Series spectrometer is constructed by the Crossed Czerny\nTurner optical design and can provide the high optical resolution, high\nsensitivity, low stray light, and fast spectral response.\nThe electronics system is powered by USB port and PH Series\ncommunicates with the PC through the USB port. It also provides 8 pin\nor 4pin I/Os for external interface extension.\nPH Series electronics operation is controlled by the RISC controller.\nSo the user can communicate to the main program through the PC\nsoftware and the protocol provided by OtO Photonics.", "price": 0.0, "discountamount": 0.0, "currencycode": "INR", "priority": 1000000, "isfreeshipmentavailable": false, "shipmentduration": 1, "_keywords": null, "isarchived": false, "isavailable": true, "applicationid": null, "productindex": 335, "imageuri": "https://productimages.withfloats.com/actual/6960ea6bf51d2d602d5b6a4f.jpg", "tileimageuri": "https://productimages.withfloats.com/tile/6960ea6bf51d2d602d5b6a4f.jpg", "images": null, "totalqueries": 0, "gpid": null, "groupproductid": null, "createdon": "2026-01-09T11:45:21.928Z", "updatedon": "2026-01-09T11:45:46.535Z", "buyonlinelink": null, "producturl": "http://WWW.COMTEKSCIENTIFIC.IN//ph-series-spectrometer-ph1014/335", "availableunits": -1.0, "iscodavailable": false, "isprepaidonlineavailable": false, "maxcodorders": 0, "maxprepaidonlineorders": 0, "uniquepaymenturl": null, "brandname": "COMTEK", "category": "OtO Photonics Spectrometer", "tags": [], "variants": false, "keyspecification": null, "otherspecifications": null, "pickupaddressreferenceid": null, "paymenttype": "None", "producttype": "products", "hsncode": null, "gstslab": 0.0, "isnotforsale": false } ], "hasmoreitems": false, "isapirequest": false, "totalresults": 27, "query": null, "floatingpoint": null }
