450nm 1.6W Blue Fiber Coupled Laser Module for Caries Detection&Caries Treatment

The 450nm 1.6W Blue Fiber Coupled Laser Module—a dental medical-grade optical light source exclusively optimized for clinical dental caries detection and minimally invasive caries treatment. Tailored to the core demands of dental clinical scenarios (early caries precise identification, minimally invasive lesion removal, detection-treatment integration, and dental chair equipment compatibility), this module leverages 450nm blue light’s optimal fluorescence excitation for carious tissue and selective photothermal interaction characteristics, 1.6W adjustable dual-power output (detection/treatment), and ultra-fine medical-grade fiber coupling. It features full dental medical device compliance, miniaturized embedded design, multi-dimensional safety protection, and oral environment adaptability, realizing one-module integration of caries fluorescence detection and minimally invasive photothermal treatment—an ideal core light source for dental comprehensive treatment chairs, portable caries detectors, and minimally invasive dental therapy equipment.

Core Dental Medical-Grade Advantages for Caries Detection & Treatment

1. 450nm Blue Light: Dental Clinical Optimized Wavelength for Dual Functional Application

• 450nm (±5nm tolerance) high-purity blue light perfectly matches the fluorescence excitation peak of porphyrin (400-450nm)—the specific metabolic product of cariogenic bacteria (Streptococcus mutans). When used for caries detection, it excites strong red fluorescence (630-680nm) from carious tissue (early enamel demineralization, hidden caries), with fluorescence contrast ≥90% against healthy dental hard tissue (enamel/dentin), enabling precise identification of early caries (no visible cavity) and hidden caries (between teeth/under fillings) that are hard to detect by traditional dental mirrors/X-rays.

• For caries treatment, 450nm blue light has selective photothermal absorption for demineralized carious tissue: the water and organic matter in carious dentin/enamel absorb 450nm blue light to generate localized mild heat (45-55°C), achieving minimally invasive removal of necrotic carious tissue without damaging the adjacent healthy hard tissue and dental pulp—avoiding the mechanical vibration and noise of traditional dental drills, and reducing patient dental anxiety.

• The wavelength is also compatible with mainstream dental light-curing resins, with ≥85% curing efficiency for light-curing resin materials at medium power, realizing the integration of caries detection → minimally invasive treatment → resin curing with a single laser module, simplifying the dental clinical operation process and improving treatment efficiency.

2. 1.6W Stepless Adjustable Power: Perfect Matching of Detection & Treatment Power Demands

• 1.6W dental-grade stable CW output (0.2-1.6W stepless adjustable) is tailored for the dual functional power needs of caries detection and treatment:

• Low power (0.2-0.5W): For caries fluorescence detection—low-intensity blue light excites carious tissue fluorescence without photothermal damage to dental pulp, suitable for intraoral scanning detection of all teeth (including children’s deciduous teeth);

• Medium-high power (0.8-1.6W): For minimally invasive photothermal caries treatment—precise photothermal removal of carious dentin/enamel, and can be used for light curing of dental resin fillings after treatment.

3. Ultra-Fine Medical-Grade Fiber Coupling: Minimally Invasive Intraoral Operation Adaptation

• Equipped with 105μm dental medical-grade UV-resistant low-OH multimode silica fiber (NA=0.22)—the ultra-fine fiber core perfectly matches the dental minimally invasive therapy probe/handpiece, enabling intraoral narrow space operation (between teeth, under gingiva, posterior teeth occlusal surface) with a small light spot , avoiding damage to adjacent healthy tissue and dental pulp during treatment.
